Battery life (all roms)

Ok folks, We know that battery life on JB is sub par. But again it's all dependant on user. If your online all day, streaming, playing games, of course your battery life is going to suffer. It's hard to compare between users because we all use our phones differently. Here's a few things that will help this is on all roms. I'm all about making my phone last all day (Texting, occasional calls, reading XDA, News, Email, things of that nature) and i can get my phone to survive my 10 hour workday without a charge and still make it till I head to bed. Here's a few things that help or seem to help... (NOTE: Current rom i am running is in my sig)
Juice Defender- Use this program to manage data.. (My setting- Off with screen off, on with screen on) I don't have 4G in my area, and honestly if i did, i wouldn't really use it unless i was downloading something large. Huge battery drain there.
Screen Brightness- Turn it down! If ya don't need it all the way bright then turn off. Autobright (To me) seems to kill battery because those sensors have to determine how bright/dim to make the screen.
Notification Lights- These will kill the battery as well (across the board) Turn them off if you really don't need. Most of us have our phone close at hand or in an area where we can hear it. So don't need extra "Hey, you've got a message" flashing at ya.
Sync Settings- Emails, Facebook and such, the more your phone connects to the network, less it's going to sleep screen off, and more juice it's gong to use. Change duration between these to make longer before it auto syncs (4-6 hours) just remember if you open the app, it's going to sync anyway.
Placebo 2.0 (Credit to devs please!) This is honestly helped alot (IMO) I run this on Shift 3 and i see awesome battery life. (14 hrs to 45% with 1.5-2 hrs screen on time) So yes, can make a difference!
Agat's Kernel (Credit to devs please! If running an ICS rom, This kernel is awesome. Nuff said!
Gtalk This app is Autosign in, Turn this off, sign out, disable if your not using. Will save you some juice in the end.
All of these things will help slightly increase your battery life.. Now YMMV depending on use for sure.. But these are a few things that can help somewhat make that phone last alot longer.
*DISCLAIMER*
I do not promise all this will actually help you in your case, It's merely some thing that have helped me personally and are typical things i do to every rom I run (which changes constantly) to ensure my battery will last longer. This is merely my opinion on things, and not a reflection of anyone on XDA or the devs we have. Thank you.
If you have anything else that might help along the way, feel free to add on here.. PM me.. Thanks folks. Mods, Hope this helps if not.. feel free to delete it.

Phone Awake

My battery life is not good lately. Someone on here told me to get better battery stats. How do I find out what is keeping my phone awake?

Not sure what ROM you're on, but you usually find it under Settings/Power/Battery Use. This shows a graph of your battery life and a list of programs underneath that have been using the energy.

I believe in better battery stats you let it run for a day or so, then go look at wakelocks and try to decipher what programs are unnecessarily causing them. I tried using the app, but it isn't very clear how to use the data. I would bet there is an xda thread devoted to better battery stats that might give you a rundown, but I don't have a link to one myself.

CM7.2. I did this and my display and voice calls which are always the biggest battery burners were twice as worse as they usually are--which doesn't make sense.
Someone told me that better battery stats would help me resolve the issue so I downloaded it.

+1. I bought it, it's telling me my phone is awake longer than the display is on, but this doesn't help me at all. I need to know what app is causing this.

I remember reading that deep sleep doesn't happen on cyanogenmod in some cases. Can someone confirm this?

i bought BBS and have no idea how to use it lol. i posted a question thread in here but no responses, ohwell :/ waste of 2.49.

K guys, I'm not going to read through this whole thread to help you, so sorry. But here is the devs thread for better battery stats
That should get you started. I imagine there are plenty of people asking how to use it, but again, I'm not reading through it to find out.

Htc one x battery dies overnight...battery stats show android os use the most.

Hi,
I have been having a problem of battery.
1. Battery dies from being 100% overnight.
2. Phone randomly shuts itself having more than 40% battery but shows 0 battery when it restarts.
3. Phone restarts quite frequently when taking a picture. (once a week)
Please let me know what should I do to solve the problem. Thanks in advance.

Could you install BetterBatteryStats from XDA? It's free for XDA members Install it, charge your phone back up, and let this issue happen again. Take a screenshot of Kernel Wakelock and Partial Wakelocks, as well as Process. Would get a much better view of what's eating your battery for breakfast.

Get Better Battery Stats installed.

I've got the same drain problem as your number 1, but not the other 2 issues. The funny thing is it only started a week or so ago, before that it was fine. I've been running the Viper rom, and Faux kernel without a hitch for over a month up until now.
I used to get a day out of the battery, and 2.5-3 hour screen on which was fine IMO, but not anymore.
I'm wondering if a recent app update has caused the issue, just speculating though, also it seems to be that the drain is happening when I'm not using the phone, when I do use the handset for whatever it uses the battery as normal.
Not trying to hijack your thread, just thought I'd give my two pennies worth as I'm having a similar problem.

I think you may be right because I have had the last 2 problems since a while and gave in HTC to repair the phone but it still hasnt been solved and I have got the first problem since the last week itself.

Did you manage to install Better Battery Stats? Leave your screenshots here when it happens again and we'll be able to help you much easier

I had an Arc before, so i thought maybe this will help:
"ALWAYS and I Mean ALWAYS reboot the phone RIGHT AFTER you have disconnected it from the computer or charger to avoid the f*king Android OS issue"

You have enough network in your area. I had this issue and change the Network selection to manual which took care of the issue.

I have full network in my area so that shouldnt be the problem.
The problem didnt occur last night...i will post the better battery stats results if the problem arises again!

You seem to have a lot of applications running and something is keeping your phone awake. Any awake time when the screen isn't on also is an application using your phone.
Go to the play store and check the permissions of your downloaded apps, any app that has the permission to keep your device awake is a candidate for your problem. Uninstall them all and your problem should be gone, re-install one by one and see when it returns.
Regards
Phil

The problem occurred again. I have attached a image of the battery stats.
Thanks in advance.

Need a shot of the 'partial wakelocks' category.
Also, don't stick them altogether into one pic, the board shrinks it massively. Just upload them individually

Here is the individual files

Looks like it's the radio causing the majority of your drain. How is the signal in your location? I see you've switched from EDGE to 3G during the screenshots... if the 3G signal isn't great then it will cause battery drain searching. It might be worth forcing your phone to either 2G or 3G only and seeing what happens.

Actually I just switched to 3g in the last couple of days. I only had 2G previously and the problem still occurred. Its funny that it happens only at night.

I think its the time for a fresh start. Format your phone and start all over.
So, how much will it takes you? Less than 3 hours? I'd say go for it.
At lest it would give you less headache and hopefully more battery.
Good Luck

I've had this problem before too, with baseband and alarm wakelocks.

First, you could've just wrote this on this thread instead of opening a new one:
http://forum.xda-developers.com/showthread.php?t=1579392
But here you are, may be the mods will join the threads.
and for the "help" you've asked, you must provide some information. Graphs, app usages etc.
also another option, the HOX (like any other HTC I've ever used/seen) can be silly once in a while when it's measuring the battery.
So if this happens very rarely, this can be related to the mesuring faults, but you should still check your power consuming stats.
you can check the default Power Usage statistics int he Settings menu, and for a little more advanced monitoring I can suggest gsam battery monitor.

Must agree, for all we know the op could have been playing on games and hammering the internet for 4 hours! More info needed dude!!!!

No games and not much use since I'm currently at work.
Ok I will check the gsm battery monitor app. Thank you.

[Q] Battery problems

Hi
'Noob' here, be gentle, please.
My original Desire is 2.5 years old. So is the battery that started playing up.
It didn't last long and the phone kept suddenly switching off at about 50%. I guess it's a pretty common problem: Htc Desire Shuts down at 40-50% battery
So, I've bought a new one, "aoonen".
The new problem is that it stacks at 15% when charging.
The LED light turns green and it shows in the Status: Battery status - Full, Battery level - 15%.
Sometimes after plugging out an back in it starts charging and shows 16-17% for some time, but soon it stops and shows 15% again.
If the phone is switched off, the LED turns to amber and remains amber, but the battery seems not to be charging as the phone remains cool and it's the same 15% when switched back on in few hours.
It's original HTC charger and cable, but I did try other cables and PC USB ports to no avail.
Factory reset did not help.
Neither did booting to recovery with wiping all caches and battery statistics.
If I replace the new battery with the old one it shows 100%.
Android 2.3.7 installed by my son (I am no expert in this) in Nov 2012.
Kernel 2.6.37.6-cyanogenmod-g2a32ab1 [email protected] #31. I still have cm-7.2.0.1-bravo.zip on the SD card and used it for the recovery.
If it's of any importance, before buying the new battery I tried using some apps (uninstalled now) that didn't help: Battery Calibration and Easy Battery Calibration.
I like my Desire, I fits all my needs and I am very reluctant to replace it.
Will be grateful for any ideas and advices.

you deserve credit for researching your problem thoroughly .
to be honest, just sounds like a fake/counterfeit battery. it doesn't look like a reputable brand to me.
you've tried calibrating the original battery and still get early shutdowns?
i take it you still need a new one, personally i would recommend official battery if you can find it, you get what you pay for.

I have wrote about same issue in this forum
You have src shots also in my thread.
http://forum.xda-developers.com/showthread.php?t=2275048
I have order new bat but I am still waiting for it.
Did you try to wipe battery stats through cwm? Battery calibration should do this but you can try manual also through cwm?
If nothing helps try new battery. Maybe new one is fake.

It was mentioned somewhere as a good brand. And what's the point in faking/counterfeiting some unreputable brand? This was exactly my thought that a 'genuine' battery is far more likely to be fake.

TBH, I have no idea how to calibrate it. I just ran the above apps (one, later another) and they said that it was calibrated, but nothing changed.

"if you can find it" - absolutely. Any recomendations?
Also, my battery is BB99100, but often I see BA S410 for Desire that looks similarly. What's the difference?

no, i've never replaced my original battery after nearly 3 years now probably should, so can't give any recommendations as to where to buy one.
it's a minefield, but be thankful that it's relatively easy to buy a replacement, unlike some new high end phones.
calibration should only be done with proper apps, this is the only one i know of that works, you have to find and follow the instructions carefully, though i've never done it myself. my battery still dies anywhere in between 15% and to 6%, which i can live with and just gotten used to. however if yours is dying at 40-50% it's likely that it's aged beyond its working life.
cwm is short for clockworkmod, he is suggesting you wipe battery stats there, but this myth has been debunked for a while that it does not calibrate the battery in any way.

me too, i dont know

Some user says there: "You must read the tutorial on XDA if you want this to work. Follow it step by step."
Anybody knows where it is at XDA?
The censored link was to "Battery Calibrator" app by Jon Richards

Real calibration is done by:
- wait until the battery is completely empty and the phone shuts down
- insert a charger immediately but leave the phone OFF
- wait until the phone is fully charged
This worked perfectly for me!

took a bit of searching around, but here
ignore the fact it is in nexus one thread, works for desire and compatible kernel, read carefully, try and see if it makes a difference.
