What happened to my battery? (Positive thread)

[ellykay]

The first week or so, I was getting 12-13 hours per charge with VERY limited use. I did the CDMA fix just in case.

Well, over the weekend, I started getting a measly 6-7 hours and started having to take my charger to work with me this week just to be able to make it home. I was still using it very sparingly, though. It made no sense, but I even called Radio Shack on Tuesday after getting down to 20% after only 4 hours of very little use. Of course, they were not really any help.

Well, fast forward to yesterday (Wednesday). I again charged it the night before, and for no known reason, I am at 22 hours with 30 percent left after taking it off the charger yesterday morning. I used it quite a bit yesterday and did not charge it last night because I was so excited to see what it would do.

I have no explanation because I didn't do anything differently. But, I hope it stays this way!!!!

The only explanation I can provide for this is that it is possible you are exiting apps different ways during your trial. I cannot remember specifically, but there are a few different ways to exit apps and I know some of them close the app while others put the app in the background. This could be the cause...

Try exiting apps you use in different methods and see the results.

The first thing anyone should do with their new phone is a master reset, that alone increased my battery time 100%. Plus it only takes a few minutes.

How is that done?

Wish I knew this sooner... hate to do it now that my phone is set up.

I'm so confused. After a week of great battery life (20+ hours), the last two days have been horrid. 6 hours of very limited use to a dead battery. How erratic. I don't know what to do or why it has reverted back.

I did notice a difference lately. I thought I downloaded an app that was causing it, but can't figure out which one. So I just turned everything off with ATK, and looks like it solved it. I left my phone off the charger last night, and I'm happy to say that at 8h:7m since unplugged, it's still at 89% with the following:

Cell Standby: 48%
Phone idle: 35%
Android System: 9%
Maps: 3%
Display: 3%
Sprint Navigation: 2%

I read somewhere that the best way to close an app is with the back arrow. I use ATK but only to kill apps that I installed. If an app is still running will consume battery. I get more than 24 hs with one charge.

I've tried everything and my bat life was about 12 hours of use. Now for some reason I'm at 9 hours unplugged with 80% left. This has been going on for the last few days...

 

[ScorpDX]

Those reporting better battery life, have you done the latest OTA update? It was supposed to address battery life and has greatly helped mine!! That could be why your seeing more life!

 

[rican408]

The ota definitely helped. But something else seems to have happened. Maybe need to calibrate the battery after the ota?

So, 9 hours at 80% would equal about 45hrs total life...why would you want to calibrate or change anything? That's great battery life!

What I'm saying is perhaps I unintentionally calibrated it since its been a few days since the ota. And the original ota only helped somewhat.

Ok, gotcha. Thought maybe you were asking if you needed to do that. I doubt you accidentally did it being that you have to repeatedly take the charger plug out and put it back in several times over about 30 minutes...not something you do and don't realize it.

That is how mine has been since the update and its got me concerned since that doesn't seem realistic. Like its not reporting or the phone is sleeping and not replicating while asleep.

I think it is realistic and the issues before the update were just draining the battery at an unnecessarily high rate. Lot of features of the phone were locked in an on position for no reason!

 

[buMitch333]

ive downloaded the update and have tried all the tips people have posted and still cant seem to get numbers like a lot of other people are getting. could it be my battery or my phone?

 

[eric3316]

No, you don't get it. This thread is different. The OP got better battery life and has no idea how it happened! Wow, what a informative thread and that is what separates this one from the other 50!

 

[musikat]

I have noticed that, too (and mine was like that BEFORE the update). Originially after the update my battery performance went down. Then I tried to duplicate exactly what I had when I first started getting 24-36 hours of light to moderate use. The only thing I can say is, for me, it seems to be all in the charging. If I noticed it starting to drop right away after it is at 100 I plug back in either until 99 or RIGHT after it turns green and it holds better. Besides that maybe it has something to do with the alignment of the planets.

I 100% agree! Never know who messed with it before you..even if it came from Sprint.

Also Advanced Task Killer will help! Available from the Market.
Advanced Task Killer - Android app on AppBrain

Set the auto kill for safe mode, and kill on frequency when screen off. This will auto kill unwanted system apps everytime you turn the screen off. Programs you want running add to the ignore list. After exiting a program like the internet or ringrdroid etc go into Advanced Task Manager and hit kill be be sure stuff is off. The program does most for you, once the ignore list is set right it takes a second to go in & hit kill to shut off programs the safe mode does not.
