Help Battery life and battery management

[Panthro]

Well, I was hoping this would be a controlled test, as I have noticed much more battery drain on the 3D than 4G when playing PvZ. Unfortunately, once charged again and powered up I noticed that GPS was on the whole time. Oops! I will retest again this evening.

Brightness was at 50%. All other settings (other than GPS) were as you suggest.

I definitely have issues with power, and after having tweaked apps and settings identical to the 4G (I was able to get 12-14 hrs moderate use) there is still a marked decrease in battery performance. One contributor, I believe, is that my signal is also weaker than 4G.

I think its time I considered a replacement.

Having a weaker signal has nothing to do with 4G and power consumption. I'm a firm believer in charging your battery up, then playing with your device until the wheels fall off. GPS does nor consume power unless its using an actual app to pinpoint a location. I leave GPS off just because I rarely if ever use the GPS function.

If you are playing on your phone with 3G and 4G on, that will cause some battery drainage. Leaving WiFi on while surfing the net on a call will eat up battery too.

Well, comparatively, I can say the lifespan on the 3D is far worse than my old Evo. Granted, I run CM7 on my old Evo (I really prefer to not have sense on my phone). But, just browsing the internet in a low signal area, I'm barely able to push 2 hours before I drop to 10-15% left (at that point I just shut off everything and let it sit in my pocket :/). Ouch. If I am to keep this one (still not sure yet), I'll definitely have to get another set of cheapo's from hong kong or something.

I can't say I was expecting much better though. Stronger backlight, much more needed for the CPU, etc.


TLDR;
A lot of factors add up to this, but in 1-2 bar signal areas, 3G browsing is far worse on the battery than the old Evo.

just got the phone today, and i have been charging it all afternoon and it finally hit full charge, how much longer should i keep it on here to max out the charging ceiling?

I think the recommended is 2-3 hours after it green lights. However, I think that is a holdover from NiCad and not these Lithium Ion ones we have now.

Can't hurt anything though

i just used my flashlight led to look for something while it was on the charger and it says the battery is 95%.

is it a trickle charge?

 

[Rose4uKy]

I'm on 21% since 11:30 this morning but I haven't done a lot. It's sitting on my desk while I sit at my computer. But I've messed with the phone off and on all day played words with friends sent a few text checked some email and read some tweets. Didn't do much downloaded a couple apps. I dont get good signal in my house neither. I've been on wifi only no 3G.

My battery life is terrible. I've made all the battery saving adjustments (turn off sync, low brightness, etc) and my battery life sucks....even without 3d usage. My nexus s had amazing battery life compared to this.

Any other ideas it what I can do to help conserve power

 

[Rose4uKy]

I don't know but mine hits 99% and then is slow and someone said it was a slow trickle charge at 99 but I don't know.

just checked again and it said it is now at 96%. idk how accurate the flashlight is, but i do believe i am going to start using it as my meter.

It's not letting me turn off sync for any of them. There is no box to uncheck. I really should be able to figure this out lol.

Menu/Settings/Accts & Sync



Interstingly...

Service code menu *#*#4636#*#*

went to battery and noticed that although I was plugged in for hours and had a full charge GREEN led, the menu indicated it was 95% and immediately when I unplugged the charge it dropped to 94%. Hmmmmm... I have not yet performed the OTA update, wondering how much that would help. 5% is not too much to cry about, but it is significant enough to say ???? lol.

BEST result I got with battery on past phone was in recovery console where the battery stats could be reset and with a full charge would allow the handset to properly gauge remaining battery life and usually made it SEEM to last longer, hopefully ROOT comes soon and we will all be laughing then.

Anyways... enjoy!

Is this battery made by HTC?

Also, had anyone had any bad experiences with off cheap brand batteries?

 

[Rose4uKy]

Yeah my battery stays at 99% for a while and then it was green and a couple minutes later right after I unplugged it I saw it showed 98%. But mine has been green and I'll look at it and sometimes it's on a 100 and sometimes it's not. But after I unplugged it and saw it was on 98 I plugged it back in and now I am green and at a 100. Sometimes mine shows green and isn't at a 10 and sometimes like now it's at a 100.

All I can say is that the standby time is awesome on this phone compared to the EVO EVO 4G, even when the phone has to roam driving within a state. If people are having problems with their battery I don't know what to tell you. I have watched some green hornet, surfed a little bit, and thats about it with my EVO 3D. But the proof of the efficiency is in the photo.

Does Pandora use a lot of juice on wifi? My battery stats say it isn't but it seems like when ever i am ising it the battery drops relatively quicky.

Posted from my 3vo monster of a phone, suck on it apple.

Panthro, can you please let us know what settings did you use to achieve that kind of standby battery? My standby is definitely not that good.

Did you put it in airplane mode, or turn background sync off?

 

[some.devil]

Just an FYI...

I had everything off yesterday including roaming. I did use some 3G and 4G sparingly throughout the day. I also made a few phone calls and used WiFi to do some web browsing. I ended up watching about 45 min of Green Hornet before I went to bed and finally threw the phone on the charger @ 10%. Total uptime was over 24:00 and total awake time was around 4:30

Much better than my Evo

If my sprint rep ever calls me back to activate my phone I will be to put I through the paces today.


Off topic:e Some.devil is that a dmb themed screen name?

Why yes it is

Big big thumbs up. i am a huge dmb fan, but that is another discussion for another day.


Is pandora a big battery sipper if it is on wifi?

I don't see why it would be, but I guess you have to take into account that you are also powering speakers and if you have the screen on you are powering a display as well.

I don't use Facebook, Flickr, Friendstream. I'm not a social networker type of guy. So nothing is setup to sync on my phone. Actually, I noticed that I did have my yahoo mail account setup to sync. Just unchecked the sync box feature for that.

My email is setup to manually download the mail upon opening. My weather is setup the same way. The email will make you setup peak times/days so I selected one day out of the week from 1200-1201. Sprint Zone app is setup to download once a month.

And I drove around with my phone in airplane mode for about 14 hours of the 98 hours. Then I said lets see what happens with airplane mode off after driving around the state. So the phone was allowed to roam if needed.

I'm at 107 hours unplugged with 46% battery life remaining since snapping that photo this morning. And I'm in a coverage area of 1 bar, if that much at my current location.

I didn't have GPS, Bluetooth, 4G, 3G, or WiFi on during my driving around the state to visit family. However, I like to leave auto brightness ON and I have run a live wallpaper ever since purchasing the phone.

The phone can definitely reach 355 hours of standby if you left it on a table and checked it a few times here and there. You would probably have to put the phone in airplane mode so it wouldn't have any radios enabled as well.

Definitely trickle.... i ran the a test using Battery Monitor Widget on my Evo(stock), Evo(rommed/kkerneled), and the 3D. The stock evo goes into negative mA after it hits 100%, even still on the charger. But the rommed(w/ netarchy sbc) evo and 3D both keep charging after 100% just at lower mAs.

Side note: Why does my screen eat my battery?

What setting do you have for your brightness display? Auto or do you have it on a number like 50%?

It eats the battery because to provide power for that brilliant screen it has to come from some place. So it comes from the battery.

I don't know if this helped or not but I got my EVO 3D. Took it home and charged the hell out of the phone with it turned off before playing with the device. It took awhile for the battery to fully charge. Once I got the green light I said, it can't be fully charged. Left the phone on the charger for another 3 hours. I had to unplug my device since I was moving from office to office that day for meetings. But anyway, once when I unplugged the phone the light turned to red after plugging it back in. Then it took like 15 minutes to turn green again.
