Battery life sucks since 2.2(Froyo)

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.

 

i've noticed an improvement as well

 

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.

 

my battery life has gone bad. takes long to charge and works half comparison to 2.1. also the home screen short cut to trun on/off different hardwares like satellite, brightness, sync and other is missing.. any idea how to get it back..? or has that been permenatly removd??

 

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'

 

I'm having battery issues also. After some light browsing, email and a few txt my phone dies at the end of the day where before i would have at least 50-60% of the battery.

 

stop complaining about the problems with froyo on your phones... its not the final version... the real one hasnt been released

 

Same problem here too.

btw we're not complaining. we're just sharing our experiences.

 

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.

 

My battery will no longer charge past 97%, no matter how long I have it on the charger.

 

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.

 

I notice better battery since I went to the new build. Way better
