I think you need to look closely at what is actually consuming the power.
Chances are that you have a rogue app that is stopping the phone from sleeping properly.
You can look at the battery stats in Menu->Settings->Phone Info->Battery Use, as this should give you an idea of what is actually using power. You might also want to download Spare Parts as this will give you easy access to additional menu items related to battery usage (e.g. partial wake usage). You can also get to these by entering *#*#4626#*#* in the dialler (*#*#INFO#*#*), but I find Spare Parts more convenient.

Hi Dave, thanx for the code it's great. However you need to correct it from 4626 to 4636 (INFO on keyboard).

Wlan_wake in Better battery stats

Hi all,
So my phone recently started giving me some battery issues that I just cannot for the life of me get resolved. I noticed that under better battery stats, my phone was avoiding deep sleep. Looking at the kernel wake locks shows Wlan_wake with nearly non stop wakes. I've done just about everything. I've wiped totally to stock Blu Kuban, tried different radios, kernels etc. I get these even on a fresh wipe with no apps installed and no sync on. It doesn't seem to be related to any application in particular. If I turn off wifi and just use 3g,the phone goes into deep sleep immediately and stays. The Wlan_wake stops and the wake counter doesn't keep ramping up. The phone once again gets great battery life while sitting idle. This occurs on both of the wifi I use predominantly, home and work. I'm really at my wits end since when I go to bed, my phones battery gets knocked down a good 20-30% in the 7 hours I go to bed. Attached is just a small sampling of what it's doing.
Any thoughts or suggestions?

Stop leaving your WiFi on. Either that or install one of the hundreds of battery scripts available that will shut off WiFi when the phone sleeps.

While I can appreciate people who want to hamstring their phones to save battery life, turning off WiFi is not an option for most people who actually use their phones for grown up things.
Sprint data is horribly unreliable for me... Without WiFi on, I would never be notified of important emails from work, done of which are time sensitive.
It's too bad that ICS has such bad battery life when compared to a similarly configured GB device.

Well a grown up would solve the problem by calling Sprint and having a free mini tower sent to them so they wouldn't have that problem... just sayin

Is there some specific reason you can't charge your phone while you sleep? It seems like that's the most obvious and easiest solution to your complaint...

I'll take a look at that wifi idle time thread, thanks man.
To the rest, when I suddenly have a glaring issue with my phone, I usually don't include "pretend the problem doesn't exist" as a troubleshooting method. If that's what has to be done, so be it. Charging the phone while sleeping is fine, depending on my schedule/battery level, but that doesn't answer the question of why the battery is absolutely horrific when the phone is doing absolutely nothing. It's not syncing, it's not pulling down data from apps etc. I guess I'm just having trouble coming to terms with the fact that Gingerbread idles, with sync on, about 3-5 percent in an 8 hour period (on blazer) while my ics experiences have been literally 10 times worse. It's hard to just say "oh, ICS battery life just isn't as good", when the disparity is that large.
I want to make sure I'm an exception, not the rule as far as idle drain is concerned.

Since I'm included in the "rest" ill say that I was not suggesting that you ignore it, I was simply suggesting that by charging while you sleep you would remedy the issue for the time being, as there is absolutely no logical reason your phone can't be charging while you sleep... including battery level... im assuming from your post you wait till the battery is low to charge, that is unecessary as Li-Ion batteries do not have a memory, so incremental charging will not damage them, in fact ive read that its actually better for them than full power cycles.... if you want more possible solutions perhaps you should start by following revampers link and using the damn search bar, as there are 10's of ics battery threads, and I'm pretty sure phaker posted a solution to a very similar issue in one of them, as opposed to starting yet another thread about an issue that's been beat to death and replying condesendingly to those who offer you suggestions not entirely to you're liking....also use the thanks button at least for revampers post as you seem to have found at least that useful, its considered common courtesy around here...

You weren't included in the rest btw. Forgot to thank v.
The first response was snide to both myself and the other person who replied about slashing off your phones arm when it isn't necessary. I have spent quite a bit of time on this problem, and have done substantial searching with my info I've collected from various apps and logs. Snide non replies get snide responses. It was not aimed at you.

This may help as well, worth a read at least... the script that just modifies wifi_supp_scan or something to that effect.... should be what you're after as I recall that was preventing deep sleep, read through the thread to confirm, I read it about a week ago and dont recall 100%

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.

[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

Wiping bat stats - you will get fresh and accurate information about new battery usage. Thats all.

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!

Settings uptime?

Since HTC managed to Bork and change some of the settings is there a way to check up time since last boot that I am missing somewhere? Perhaps even gsam or BBS? kind of upset already missing my android battery stats graph but irks me even more I can't check my uptime. Actually a very important stat to me.

Thanks. That was helpful but I meant total uptime. Like when you reboot it resets tour total uptime which is usually in settings>about>status>uptime.

Did you try *#*#4636#*#* it'll show a screen with Phone Information, Battery Information, Usage statistics and Wi-Fi information. In the Battery information area it gives a "Time since boot" which I suppose is effectively total uptime.
Unless you want something that adds up the amount of time the phone was on since you actually bought it then I don't know...

Suhweet. thanks a lot dude. that code works but I use viaero 4g toggle to force LTE only sometimes. the info I wanted is since last boot and it there under my nose all along. it helps knowing if my phone crashed/rebooted unknowingly like when charging at night. very important especially if you start tweaking your phone. thanks again.
