Got a Desire Z, but the battery seems to go down too fast, even when not in use. Same thing when the phone is off also.
I get around 5-7 hours of the phone being on with about 15mins use and the battery is dead.
When the phone is off, I get about 8 hours.
I know its not the battery as I've tried a few. Ive also tried a few ROMs aswel as stock ROMs.
Any ideas on how I could fix this?
Thanks

Every time you flash a new ROM you're wiping the battery stats and it takes the OS a few days to re-learn your battery. Wipe the stats manually and give it a few days.

Yea but how long do you wait before you end up reflashing or wiping again?
Around 3 days.
Have you checked to make sure you don't have some sort of errant app that's causing your battery to run down?

x2 this happens a lot especially going from ROM to ROM. The built in function works ok, but I generally use Android booster to narrow down errant specific apps even built in Android apps like sync. It helped me go from 15 or so hours to 24+ especially if you use autostarts and TB to freeze or prevent from startup
3 ish days is probably not enough for Android to learn the battery levels properly. It takes a few charge cycles to get the values right. I wouldn't have thought its good to wipe battery stats constantly.
With the Touch Pro 2, you could force a learn by discharging it completely until it doesn't power on the firmware any more, pull the battery for a minute, charge overnight while powered off, pull the battery again for a minute then power on. This updates the values in the firmware too.
I have read it works with the Desire Z too, and I've tried it after a ROM flash just to wipe. Obviously, while you can still get into recovery, wipe battery stats prior to this.
Disclaimer: Do this once only, its very bad for Li-ion batteries to repeat this. Do this at your own risk.
If that don't work:
If it does it in airplane mode then its probably an app.
Make sure you flash something like a rooted stock ROM and make doubly sure you wipe everything before first boot. Data / Cache / Dalvic cache etc.
If you haven't installed any apps and it still does it, RMA the phone for repair / replacement.
Hope that helps!

Thanks for all the help above. Will try for a few more
Days.
Though the battery even dies when the phone is off.
Well, Ive still got the same problem. Ive realised aswel, when the battery dies and I go to charge it up the orange led flashes for around 5-10 minutes and then turns a solid orange.
Same thing happens with a replacement battery.
Im guessing its probably a hardware fault

I've had the orange led flashing before after a completely flat battery. Its probably something to do with a dangerously low voltage from the battery. Its extremely bad for Li batteries to get very low..
Have no idea. Must be sg wrong with the HW, get it to a service station or ask for replacement where you have bought it. Mine goes for days. (bought in Austria, factory unlocked, Android 2.3.3)
I might receive my new Seidio 3500mah extended battery today for the Galaxy Nexus, and I'm not sure if I need to do certain things before installing it, to those with experience.. do I simply install/power up the phone/start charging? or do I need to keep my phone off and start charging? does it make any difference having the phone On or Off the first time you install an extended battery? I read on Seidio's website that they recommend to keep it charging for at least 3-4 hours after it's 100% charged, would that be the procedure with every charge..?
And do I need to Wipe Battery Stats before installing it? it's things like these that came to my mind, I just wanna make sure I'd do the right thing the first time I have it on.
Thanks everyone. :good:
IMO, I just install the new battery and turn it on and charge it to 100 then use it as normal. The very first time it might go down fast but after a few cycles it should improve.

Is "Wipe Battery Stats" needed? and do you need to charge it 3-4 hours every time it hits 100%?
Thanks.

Not sure if it's necessary but I would leave a new, extended battery on the charger for at least an extra hour after it says "Full". Other than that, don't worry about wiping battery stats, that has become an unnecessary procedure these days. Only very rarely does it seem to help anything and even then it is debatable.

If the phone says it has a full charge you can take it off the charger. Every time you plug the phone into the charger it wipes it own battery stats to make new ones for that new cycle.

No, just the first time. I do it as more of a "superstition"-type thing, not really based in science or fact. :silly: But, I have always had good battery life with new phones/batteries (fingers crossed) so I don't plan on stopping anytime soon. Other than that, you should be fine. My phone has taken well to my extended battery without having to do anything at all.

Thanks a lot man, my battery for some reason didn't arrive yesterday , hope I'd receive it today or so, I'll call them up later today when I get back from work.
Appreciate your responses everyone.
So after the pass couple of months I've been getting battery drains, for example losing 1% after 5 minutes while on standby and had to charge every night
Last night I was out for a long long time and the battery drained with normal usage until I hit 18% (with about 14 hours off the charger) and it stayed there for quite a while. I was sending texts, outputing music in my car,using the GPS/Maps and the battery stayed at 18%. Was using data and brightness was around 25%.
I've been wiping battery stats every week, I don't know why but I got in the habit after this battery drain issue.
Is there any way to fix this? Probably not :S
Wish I knew, man. My PLAY stays on 100% for a REALLY long time, then drops much more quickly once it finally gets to 99%

Battery drained all the top 16% and the next time I woke it up, it went back to 18%, this is so weird!
Sent from Xperia PLAY running Gin2JellyBean
all your claims happen to me, too. and i think they're normal.
I would suggest 2 things.
Stop wiping the stats first. You dont need to do this anymore. Your stats level out tge more it is used. Just do full charge/discharge for a week.
Second would be to look for a rogue app running in the background.

happen to me after restoring from nandroid backup, battery is not discharging, it charging instead, even when i didn't plugged it to ac adapter,
fixed the problem after wiping battery stats & re-calibrate battery by totally drain it and full-re-charge after. Also defined battery capacity using Battery Widget,
Mine stays at 100% for a long time too, then drains fast till around 90% and work ok after that i guess.

Mine doesn't even charge It always stays below 10% When it's plugged it, there's a solid red LED (not flashing)
I think the battery ie 20% n after u left it, it move a bit say 23%, that is coz of the oc'd u've been doing. Each frequency hav diff volt. So the more u use the more it pulls. And when u finally let it down the un-wanted un-necessary volt is return back to the batt. So its normal. Its like a rubber bend or something similar. More tension means more power, when there's less tension it revert back to its form with a bit lost of physicality. Hope y'all understand what i'm getting at. The phone batt indicator is correct. U should always watch ur oc frequency. Hope thats explains everything

Fair enough but its all in your head. It's just not how it works. All batt stats is for is the battery usage window.
Anyone ever have issue with their battery fluctuating? It pretty much yoyos up and down without me even touching it.
I have calibrated multiple times.

That can come from many things. I would suggest to get BetterBatteryStats and see what drains your battery. Can also check under settings/battery to see what's draining it.

Well I'm not necessarily talking about battery drain. But fluctuations. it goes up and down. Drastic changes. Say 50% one sec to 70% a few minutes later. Sometimes the phone will go down to 1% and power down, but when I turn it back on charge could be 30%.

Sounds to me like you need a clean flash. Backup your stuff, wipe everything (don't format sd), and start back fresh.

Sorry, it's not very clear. Did you do a clean flash? If so, try to do the factory battery mod (a little search will get you to it). It's a manual way of reseting your battery but must be done when fully charged.
Also, when you cleared your battery stats, did you do full battery cycles?

BATTERY CALIBRATION
Hi!
As we know when we install a new rom we sometimes have battery drain or when we flash a new kernel etc..... what is this?? this means that your battery goes to 0% very quickly!
The normal steep is goes to recovery and wipe battery stats!!
but what i do if in recovery don't appear something like wipe battery stats??
simple!! be sure that your nexus is completely charged,download this app ,, tap on battery calibration !! (after that charge your nexus without break)and congratulations.... buy a beer and make a party!!
I don't made this app.... just share it....
i will upload the link in a note pad... why?? simple.... i can't put links!!!
There is no need for battery calibration. Just discharge to 0% then charge back to 100% and you should be good to go.

It doesn't even need to be to zero.
Everyone should go to batteryuniversity.com and read the articles on cycling and charging li-Ion batteries. Then you will be able to make sense of conflicting advice on batteries.

The myth of wiping battery stats was thoroughly debunked almost a year and a half ago. It is a 100% true statement that neither this app nor wiping battery stats in recovery has ever affected anyone's battery life or battery indication in any way, shape, or form.
Want to know why battery drains after flashing a new rom or kernel? Hint- it has absolutely nothing to do with incorrect battery stats- totally disregarding the fact for a moment that batterystats.bin has absolutely nothing to do with battery charge indication.. After flashing a new rom, your device is actually using more battery than usual as accounts are set up and synced. Likewise, after flashing a new kernel, it takes a short amount of time for the kernel to "settle."
If you still believe the myth that battery stats need to be wiped every now and again, there's an even easier way to do it than wiping in recovery or using some snake oil app... charge your device to full or near full and then unplug it from the charger. Voila- you've just successfully wiped battery stats!

Strange battery behavior
It's actually odd, my battery started getting stuck at 100% like a week ago or so, after 11 hrs standby time and 30 mins screen-on time, it doesn't even drop 1%. However, it shuts down normally at 1%. I actually tried so many things to fix this, i opened the back cover and pulled the battery out, i let it run dead and charge it all the way up, but it just seems to like that 100% mark. Since it actually shuts down at 1%, i wanted to make sure it's completely dead, so i booted into recovery and oddly, with max brightness in twrp, it took about 15 mins for the device to completely shut down.
Any ideas what might fix this?

Bear in mind that you optimally do not want to discharge the battery to the point of shutdown. Doing so shortens its lifespan, and can trigger the N7 to go into a hibernation mode on order to protect the battery from permanent unrecoverable damage due to a deep discharge.

The app has nothing to do with it as the only thing it clears is the list of processes that have operated on battery since the last full or near full charge.
The only "calibration" that an end user can perform entails a complete discharge/charge cycle. This resets the flags for the battery's internal fuel gauge.

This is all the recalibration the device needs.
Naja is 99% correct. It's not the only calibration you can do (you can wipe stats), but it's the only one you should need to do.
batteryuniversity.com has a couple of good articles on the care and feeding of Li-Ion batteries. There is a lot of less than accurate info that floats around about batteries. The above site is a good way to learn the difference.
