With very light usage, I've managed to get my Evo3D to last just shy of 2 and a half days. When actually using it, it's been a bit hit or miss, some days it tanks pretty fast, other days it's done quite well. But one thing I have noticed is that sometimes, especially around the 35% range, it'll spontaneously drop 10-15% (it actually did 43% straight to 14% this afternoon). It's visible in the battery use graph as a sudden nearly vertical line. It's never happened when I had the screen on actually doing something, it just happens randomly after turning the display off. Has anyone else seen this? It's pretty confusing.
First thing is first....
Did you download spareparts and see what is consuming battery? In other words, check for a wake lock.
You have to give the battery time to get conditioned. It gets better the more you go through charging cycles. I'm at 75% after 8 hours of moderate usage and that's pretty consistent for me.

For the first week or 2, the phone has a hard time understanding how full the battery is. Try draining it down to 50% or so, and then resetting it. You'll probably see a sudden drop or rise in the battery%. Resetting it will force the issue, but it can also happen while the phone is on. That's pretty normal till the the phone "Learns" the battery.
It doesn't mean you suddenly used 15% of your battery, it would probably explode if you did that... it just means the phone re-calculated the battery's life and changed the number.
Your not alone as soon as mine hits 35 percent ill shut the screen off and here it beep at me and bang its at 14%. lol same as you.
Don't know if it will help you.
I had a similar issue as you, battery would get to around 30ish % I could turn the screen on check an email, set it down and bam 14%, and the low charge noise.
I wasn't trying to fix it, instead I was doing this http://forum.xda-developers.com/showthread.php?t=1153371
When I attempted this I had about 35ish percent battery left, following the directions my phone restarted when it came back up I got a 1% battery warning, then my phone went into emergency shut down. I thought something happened and I was going to have to return the phone. I powered it back up and it read 33%, from there on out my phone now drops a % at a time, and my battery life is as good as the other people who get phenomenal battery. I'm going on 48hours with light usage and still have 25% left. I've txt'd music, videos, nothing heavy.
Take it for what it's worth, I don't know what happened maybe the data reset, resets the battery calibration, I have no clue, all I know is what happened to my phone and the result.
So got my S3 yesterday, installed some apps, etc. Throughout the day, battery life seemed respectable. Last night, I charged to 100% and let it sit overnight with nothing running. I woke up 7 hours later agreed and my battery was unfortunately at 81%.
1) The first problem (and this may be related to the battery standby usage) is that it claims I had No Signal and No Data Connection which was untrue.
2) The second problem is this "wlan_rx_wake" and "sec-batter-monitor" kept the phone awake.
Any ideas?
First impression for me is that this isn't an issue. I have sync off and update only when charging. Went to bed @95%, woke up it was 92%.
I did notice that it seemed to take a bit longer (than the One S)to get up to it's first full charge yesterday. This might have been my imagination though. It is a fairly large capacity battery.
From my experiences with new devices and even flashing new roms and updates. Give it a few days to cache and cycle. Then once the battery gets broke in you should be able to share your charging / discharging experience. I would rule it out as a hog yet.
This happened with my most recent firmware upgrade on my Asus transformer prime..Updated, drank juice, now after a week its better than ever.
Plus with everything you have on Bluetooth and such that can REALLY drain a phone..
I agree with discharge cycles and OS calibration but there shouldn't be wakelockers engaged.
Turned off WiFi, now there is a "deleted_wake_locks" under kernel wakelocks. What is that? Lost like 4% in 90 minutes of no use and "deleted_wake_locks" engaged the phone for 80+ minutes.
Does anybody know how long the notification light keeps blinking after getting a notification? I woke up in the morning and the light was blinking and had a text message from about 4 hours before the time I saw it. The blue LED was blinking. I hope it doesn't stay on until I see the notification since it's gotta use some of the battery.

That's pretty much the point of the LED - if it only lit up on arrival you'd have to be staring at the phone all of the time. But a flashing led like that should have a tiny impact on battery life.
there is a thread or two in the I9300 forum about cell standby, wireless wakelocks and battery drains. i was hoping i wouldn't hear about this with the US version but it looks like something similar is happening.

You have one bar in the picture.. is that the same place you left your phone overnight? Even if you have signal albeit low signal your phone gives the radio more power in an attempt to hold onto that signal. That could have something to do with it. Also, I guess wifI is holding a wakelock :/

i have to agree, low/no signal sucks bat life big time!
looks like wifi and bluetooth wer in use the entire time....
another tip, when you get done charging it, reboot it.
me personaly, i charge my phone while im asleep, then unplug and reboot as im headed out the door in the am...
to me it seems smarter to start the day with a full tank than a partial one and wind up hunting for power later....
i have no complaints about battery life..i have been on the same charge for 15 hours with light phone calls, heavy texting and web surfing, and my battery is still at 36% and this is only after my first charge cycle so i am guessing it will only get better after a few more cycles
After a few days with my SIII, I can say that the battery life is not quite as good as the One S I had briefly. It is however way better than the G2x, Evo, Indulge, and Sensation.
I will be getting at least one spare battery. I did not like having a captive battery in the one S. Keeping and using spares is not an issue for me.
First charge not bad

I have an Atrix 4G running Neutrino 2.9 EE, with a new battery I bought only a few weeks ago because I thought my old battery was dying. But I'm having the same problem with this one. I can't get it to charge past 70% or so, and the charge seems to drain very quickly, about 1% every 15-20 minutes. I checked the battery usage, and Phone Idle is taking up around 60-70%. I've got wifi off, the screen turns off after one minute, and the brightness on half. I'm really at a loss as to what's causing this, so any help would be great.
Battery stats

Try to use all battery till your phone turn off, when charging again go to recovery and clean battery stats, rebbot and charge to full battery, see if your bar go to %100, i install battery widget and have an option for motorola phones, enable that option, that help me a lot,
Good luck!!!:fingers-crossed:

Battery drain issues, it seems, are as varied as "My car is making a noise that goes like this: ____"
Do you have the battery calibration app off the market? A full charge is 4200 mV (or really close to that value), regardless of what percentage your phone is displaying.
If your phone is getting up above 4100 mV, then the battery is fine. You can trick the phone back into displaying a more accurate percentage for a while, but it's not permanent:
- Charge the phone as high as it will go
- Shut the thing off and pull the battery
- Plug in the phone, wait for the question-mark icon to appear
- Re-insert the battery, let it sit for a few minutes (10? 20? no magical number here)
- Turn the phone back on. Percentage should be a lot closer to 100%.
If you're getting a decent charge but the battery is genuinely draining quickly, well... all I can offer is my experience from this summer. My major symptoms were:
- Losing an entire charge in the course of 8-9 hours, but ONLY when wifi/mobile data were turned on
- *Extreme* phone lag when wifi/mobile data turned on. Every single app would force close. Not fun at all.
- Checked what's using the battery, and "Contacts" was responsible for ~5% of the charge.
After six weeks of debugging hell, wiping, reflashing stock, etc I found out my contacts were nonstop-syncing (and duplicating, and duplicating, like rabbit offspring) on one particular email account. Killed the email account, got a functional phone back. Battery life returned to normal. All that to say, one misbehaving app (even a stock misbehaving app) can trash the phone's performance.
If you can stand it, try returning to something completely stock and not restoring any of your apps/data for a few days.
Have had this phone for about 2 - 3 weeks. Starting yesterday, I noticed the battery draining abnormally fast. I am not using any email client other than gmail. So basically, nothing in my routine changed. I didn't install any new apps, or started using any apps that I wasn't using before. Essentially, out of the blue, my battery is draining like crazy now. I had to recharge it mid day yesterday, had about 30% left before going to bed, woke up and phone was dead.
This is the s6's battery..i go out at 8 and at 12 my phone shuts down..buy an external pack and youll be fine

The reason I made the thread is because the battery was fine for me until a couple a days ago, now it drains 30% over night and I can barely get through half a day on light use. One problem after another with this phone. I guess I have to do a factory reset.
Booting into safe mode could tell you if the fast drain was caused by a rogue app.
Hi all, this may seem like a strange question.
Just got a new Mate 10 Pro, and when I switched it on for the first time the battery percentage was at 42%. I've read somewhere that as a general rule for new phones, batteries are normally between 50 and 60% out of the box, and if it is anything less this could be a sign that the battery is faulty (e.g. can't hold charge for long). Also my last few phones have actually been around 50-60%, so was a little concerned to see it at 42%.
Does anyone know if this is true or what I've read is a load of rubbish?
Don't want to return phone but will if I have to.
Thanks.
I had mine with 34%. Some even got them at 0%. Try charging and see if it charges fast. And then use the phone. If all seems normal than there's no problem.
But that's is really weird,i saw 3 new mate 10 that came with dead battery, I'm sure that's not normal.
I'm thinking that while the phones were shipped they turned on automatically and drained the battery.
..
I spoke to Huawei and they say they've had multiple cases of battery being below 60% due to phones being accidently turned on in transit. They suggested charging to 100%, then leaving phone in airplane mode overnight with all apps closed and seeing how much the battery drains. Anything above 96% is a good battery apparently.

Same here!!!!
Completely dead!!!!!
Mine was stone dead out of the box. Zero %. !!! Charged it up.... took an hour and a bit to get to 100%. Used it for just over a week now and battery is fine and dandy... Drops a couple of percent overnight... Lasts forever during the day. Really is a monster battery. Seen quite a few reports of zero % out of the box (which is pretty unusual....most phones I've had seem to be about 60%) but doesn't seem to be an issue... maybe that's how they ship them now...for whatever reason ???? Anyway, seems to be a non-issue.
Same thing. My first mobile with dead battery after I opened box. But about 10minutes I had same percent I can use.

mines had 12% i never switched it on plugged in the charger as i like to start with 100% battery while setting up a new phone.
Guys, the battery measurements seem to be screwed up at first. Even when I switched phone off, it drained like 10%. However, after about 3 full charges, everything is great. Still at 100% in 2 days (yeah, I left it off for 2 days just to check). So, my theory is just that the phone needs to calibrate its measurement of the charge percentage.
My pro came with dead battery too.
Same here, dead battery. After first charging, is working just fine.

Mine was around 60%
My Mate 10 standard was at about 87‰.
Mine came dead too, i was very concerend and also started a new thread about it here. Relived to see that many have the same "problem" so far I am loosing about 10% overnight with wifi and all enabled. Seems a lot to be honest but I am going to try it for a few weeks to see what happens...

With wifi, there might be some background app processes running that are draining battery life. Try it without wifi. You should lose less than 5%.
mine completely dead on arrival...I also notice that the power button easily press n get the phone to restart few times for me...
They're supposed to charge it till its full on the first time to optimise it
I'm surprised so many Mate 10 Pro's have been delivered dead or with minimum percentage. Mine switched itself off at 10% so seems like there is some calibration issues too. Hopefully these will work themselves out after a few charges, not sure if it's because the phone is so new (maybe first batch niggles?), but didn't have any of these issues with my Mate 9.
How are people's batteries that came dead or with minimum percentage performing so far?

Very well, no issues with battery life so far. Mine came dad and acted up quite a bit in the beginning.
