Default Battery life sucks since 2.2(Froyo)

Since Froyo, I've noticed a MASSIVE decrease in battery life. I haven't been using it anymore than I normally did, either. And no new major apps or anything.

I'm very disappointed.

Anyone else experiencing the same?

other people are complaining the same, others are saying improved.

actually on the first 2 days i had froyo, i went 30 hours without an additional charge. then after today i went just 6 hours of light use and already my phone died.

i guess it's just the beta froyo. not too worried about it.

I'm noticing an improvment. I now get ~18 hours with heavy web/email/podcasting/bluetooth usage. The battery meter seems more accurate now... more linear.

My battery life seems good on Froyo, however yesterday it had trouble charging for a while, despite being on the mains for about 4 hours it only got from 0% to 53%

Later on, it was fine though.

The power control widget is still in 2.2??? As to my experiences, everything is pretty much on par with 2.1. Flash will suck the battery dry, but otherwise I am not noticing any differences? I wonder if there are differences with regard to obtaining 3g or wifi signals?

Get it back with a long press on the home screen, select widgets and find 'power control'

Default Just my FROYO observations... about the battery life.

W/ stock unrooted 2.1 (T-mobile)
(according to the app "System Panel app/ Task Manager")
My Nexus Ones Cpu used to go all the way up to about 998 Mhz (estimate) and drop back down to a 200-300 Mhz area...constantly (every few seconds or so if i recall) with not much running at all..(so idle time was slamming the cpu) this was one of my guesses as to why the battery life sucked.

The other reason.... i suspected... was that whatever is used to calibrate the battery level was flaky. It would go from 100% down to 90% it would seem in about 20 minutes...after that (90% or so) it would seem to stabilize a little. Although when i first got the phone battery life really, really sucked.
I am a moderate user not a heavy user. After doing 3 sets of conditioning it got way better...except for the above mentioned behaviors. With that said after the phone stabilized i got about 12 - 14 hrs consistently.

Now fast fwd to 2.2 "Froyo" (manual install)
Better CPU power optimization...
CPU now fluctuates from about 278 - 333 Mhz "with not much running at all"
if i slowly scrolled up it would be at 278 - 560 or so. (never went higher than that average and certainly no where near max cpu.)
CPU about 278 - 693 with rapid scrolling... again still never shot up to anywhere near max cpu.
After opening and running some apps it will shoot up to max cpu area....
So in theory this optimization should add to the standby time at the very least... in turn getting longer battery life.

I get way better 100% - 90% battery life. (one observation was 2-3 hours...instead of 20-30 minutes)
Also the Android battery icon in the notifications seems accurate now. (may end up ditching the add on widget i got, to monitor battery level)

I have noticed much improved battery life. If you do not get better battery life with 2.2 try at least one battery conditioning set ( fully charge battery until it is 100%...(not when the indicator light is green cuz it will do that at 90%) then run your phone without charging it at all (whether power plug or USB) until the phone shuts itself off. Try that at least 1 time if not 2. I got crappy battery life just after the manual install the first 2 days... until i did this. It maybe coincidental, but it can not hurt to try. It will take a few weeks to get an accurate hours of battery life... but you should all see a an improvement. If not my guess would be some incompatible apps. Example...I did use Helix launcher in 2.1, but it FC constantly so i installed Launcher Pro. Just this morning there was an update that now lets you add shortcuts too the bottom, just like Helix. Launcher pro is very fast too.

One last thing of topic I guess... as far as a new feature in FROYO... i have not seen this mentioned yet but there is now the ability to adjust the text size in Gmail app (like you can in the web browser)...but sadly not in the basic "email" app. So i can now read my emails (in Gmail app that is) without my glasses LOL

I m also facing this problem.For the first day,when I got Froyo,the battery was good and I worked up to 16 hours and the day after the hours get reduced and now its dead.Now the situation is that I have to put the battery connected to the charger while using Froyo.

I think that my battery life is slightly better. But I have noticed that the phone charges a little faster when it's plugged in and turned on. Has anybody else noticed this or I am I just delusional?

I posted this on XDA....

I noticed massive and quick battery drain and constant 3G connection once I upgraded to Froyo. This accompanied a very hot phone. After watching my cpu use and memory use I determined the Push Exchange was the culprit.

I simply turned off Push and then turned it back on. Once I reset this setting the battery drain immediately stopped, the CPU use dropped back to normal and the phone cooled off.

I think that the Update to Froyo rather than a fresh install has messed up a bunch of settings. The best thing to do is systematically go through all your apps and reset the settings...unless someone else has a better option. Also, I have been clearing all my caches and this has helped.

Battery life and a few other issues were solved for me by doing a factory reset. its a bit of a pain getting everything back to how it was but it worked for me and my N1 has been faultless ever since.

simply solution: buy an extra battery for $25, keep it in your pocket; you'll be amazed at how handy this is.

A simple solution it may be, but why should I have to pay more money for a phone to work like its supposed to?

I am appalled at the battery life on the N1 with Froyo. With 2.1 this phone was barely manageable getting almost a day out of it. Now, I only got 9 and half hours out of it yesterday and it died on me on my way home. I have NEVER had a phone die on me before as Ive always regulated my use and kept an eye on it. This phone just sucks now, literally. I watched the battery meter go down like the gas gauge on a Dodge Viper.

If the phone keeps up this way then Its, for me, completely unusable. I dont care what its capable of if its not capable of staying on. I dont see this phone staying with me much longer if it keeps up this way.

It sounds like you might have a bad battery. I would either get a new or call up HTC and see if you can get them to send you a new one for free. On a heavy to moderate use day I usually get at least 12-14 hours out of the battery (a bit more because I switch batteries or charge it when it gets to like 20%).

HyperM3, it may be possible you have an app installed that isn't FroYo friendly. I did read somewhere that someone was having terrible battery performance after updating until he uninstalled and reinstalled his homescreen widgets. That cleared it up for him. Might be worth a try for you.

You can use SystemPanel App / Task Manager for Android to monitor your apps and check if there's one hogging the cpu. I seem to have worse battery life aswel and started monitoring today. But I most likely have bad battery life because I'm testing all kinds of flash sites

Sounds like a BS response.

True story:

I was at a friends' house, while I was showing Doodle Jump on my Nexus One to my friend, our other mutual friend whips out his new iPhone, very excited to show he has Doodle Jump also...

As my friend proceeds to play Doodle Jump on the Nexus One the iPhone is still struggling to boot the game, suddenly our "iPhone friend" jumps for joy that the game has finally booted then he begins to look disappointed and sad as his iPhone dies, battery died and he has no charger he is dead in the water.

As my friend proceeds to play, I notice the Nexus One battery also is about to die, I show our "iPhone friend" how easy it is to take the back off the Nexus One and I slip the extra fully charged battery in my pocket into the Nexus One and all is good for the rest of the night, even with extreme game playing.

When Apple begins to make iPhones that you can easily change the batteries on then perhaps they will be in the same ballfield but at this point they are not.

You saying my response is BS? Oh, sorry, I am new to phones and therefore I should have to understand that they arent supposed to last or be well protected. Therefore I need to buy the accessories to make them actually do what they are supposed to do.

Ive been using cell phones since 1997, yes, I had one of the first startacs!

That being said, this is the first phone Ive had that the battery life is stupidly poor. My Bold 9700 would last 2 days without a charge. My Nokias would last 4 days without a charge. I cant have my only phone(personal and work!) not make it through the day. I should buy another battery and accept the fact that the phone sucks it up? Thats a BS response. Like I said, I cant wait to be out of this phone and onto something else that will actually work the same but last longer.

Aside from this, today the battery life lasted significantly longer. I dont know if it just had to get used to the new OS being in there or what but Ive gotten about 12 hours out of the phone and theres still 28% left. Im almost ok with that.

Ok, I have to give an updated response. I dont know what it was about the first day but so far yesterday and today have been totally different. Actually today has been awesome. Ive been using my phone for over 12 hours and it still has 50% battery life left. Thats completely more than I could have hoped for in the upgrade.

I am much happier with the phone now and my mouth is full of shoe.

Default This is my theory

And my theory is this. The brontosaurus is thin at one end ... oops, wrong theory.

I think FroYo needs to get to know your battery because it doesn't speak éclair. The day after I updated to FroYo my battery level went from 97% to 88% in 20 minutes and then hung in the 60% range for 4 or five hours. Then it took a nose dive and was down in the twenties two hours later. At around 4:30 it warns me that the battery level is 15%, but within 5 minutes it shuts itself off. When I plug it in (in the car on the way home) it reports a 0 battery level. After a complete charge, it's behaving normally again, and perhaps a bit better.

I dont know what it is but my battery is SO inconsistant. The day before I had posted about amazing "second day" battery life. Then yesterday my battery kept dropping again with very light use, had to charge it up mid day. This morning, I took my phone off the charger and it was only at 99% after 6 hours. Then as I was sending a few texts and checking some emails I was watching it literally tick down 97, 96, 94, 92, 88 within the span of 5 minutes. I put it back on the charger and a half hour later it said 87.

WTF???

The display is just because you're playing with it more now
But I have noticed the browser being more of a hog aswell. What browser are you using?

I know I started this thread a while back, but eh... I don't have this problem anymore. I was stock, unrooted, running the manual FroYo updates.

Rooted + custom FRF91 rom + undervolted + SetCPU = win

24 hours of normal daily use puts me to roughly 40%

I had battery issues as well, then I stopped a few things like the GPS location feature,( I think that’s what its is), I also darken the screen from full brightness I took it down one notch, I also used the *#*#43 ........ code and changed the radio to Auto PRL, now I can go a full day with the battery on moderate use, few calls few SMS, some browsing, a couple of widgets going on the back ground,(soccer scores) I also have a widget to turn WiFi on or off, and only turn on wifi if I know the network is active. Now battery last the whole day no problems. I do carry a spare for emergency and did not need to use it since the 2.2 update

Nope...I've gone back to my iPod for music since the 5 hours scare me >_>;; And I don't watch videos or youtube. the 3 hours I was on the phone, I was simply on AF or reading an e-book or on the MSN app...nothing that I consider MAJOR battery hog.

I'm on 2G with GPS off...

Something I have noticed...my WIFI is also bad...well not as good as it was. I left it on overnight with the phone in sleep mode, in 6 hours (when I unplugged the phone) it went down 15% (before it'd be 3%) and 5% was WIFI (left it on just to see how much is being used by wifi). With 2.1 my WIFI would show a 3/4% drop with 16 hours battery life.

I cleared my cache setting...but still not seeing much battery improvement.

Is your Wireless n or g? I think n is supported in 2.2 and you may need to remove the settings and reenter them. Just a thought.

reading an e-book, MSN app, so interacting with the touchscreen and keeping the screen 'awake' all the time, the apps may not be a MAJOR battery hog, but maybe the consequent use of them is.
By the way, I think GPS only activates when an app that requests some location is active

Yes, but this is how I regularly use my phone for and it'll last around 16 hours...now it's 5 hours with the same activity. I'm going to uninstall some more apps...I'm still thinking there's an app that's not playing nicely with 2.2.

An oddity I noticed last night, that it seemed the battery was still charging even though it was 100% full...when I had it plugged in (after it is fully charged), the phone was still REALLY hot (around 40 degrees). This has never happened to me before, when I left it plugged in (after being charged). I'm not sure if it's still charging...but it FELT like it was. Is anyone else experiencing this?

Been doing a little testing and here's what I'm getting.

First the setup:
Stock Nexus One on AT&T, about one month old, Originally with Éclair 2.1 update 1 then manually updated to FRF83 then got the OTA to FRF91. Using AWDLauncher with 5 home screens and the following widgets ... Stock media player, stock YouTube, Google calendar, Google search, SwitchPro, The Weather Channel and Beautiful Home. Screen brightness set to Auto, 3G on all the time as is GPS. WiFi off unless needed as is bluetooth. Push email checking 3 POP3 accounts.

Currently loaded apps are Task killer, SwitchPro, Voice Search, The Weather Channel (yeah, I am an aging weather junkie, so sue me... oh and don't forget, all you kids, stay off my lawn, too) Amazon, Email, Facebook, Clock, YouTube and Gmail. 212M available.

The results:

Charged battery to full from 10% and unplugged yesterday morning. With relatively light use as summarized. Showed a 6 minute YouTube video to a friend (iPhone vs. EVO cartoon), sent and received some texts -- maybe 20, checked email at least every hour, installed two apps from the market, browsed for a total of around 45 minutes and had 30 minutes worth of airtime on actual phone calls, oh yeah, took 4 pictures, too and took the dogs out to pee using the LED as a flashlight (5 minutes, tops).

This picture was from about a half hour ago.



As you can see it was on for over 28 hours and the indicator said I had 25% charge left. I am now approaching 30 hours, after using the screen for most of that time to review the widgets and running apps for the lists above and it's down to 23%.

If this continues, I will be a very happy camper.

What is your screen brightness? Display usage seems low...
