Lumia 920 battery life worse after Amber .. Anyone suffer from this issue?
Before I installed the Amber update on my lumia, my battery life was way better. I used to get around 1.5 days of battery life with low usage (3-4 hours talktime, 1-2 hours wifi on, 1-2 hours of video playback, 1 hour gaming). But after I have installed, I get a constant battery discharge rate of 3.5 % even if i am not doing anything. It's highly annoying as I had felt that Nokia/Microsoft had to improve the battery life and Amber is just worsening it. I read a few posts here how it has helped out people here so I am confused on why it isn't happening for me.
I have disabled glance, double click to unlock, only allow one battery app to run in the background task everything else is disabled, nokia drive,location,nfc etc all disabled

You have to retrain the charging system. During the install of the new ROM it assumes that the current battery level is full charge. So if you where down to 80% when you installed, it now thinks that is the full charge level. Mine would not last for 5 hours on standby once I went to Amber. But I used a battery killing app to completely discharge the battery then let it fully recharge without disturbing it and now may battery can go for twice as long as it did before Amber.
i notice in Amber, if use any battery status monitor, battery consumption is much worse... after uninstall battery life is much better....
also for better battery life, kill auto mail check
for data connection, when you not use phone switch to Edge (2G) instead 3G/4G... is slower but less consumption...
turn off or increase mail checking time

Hi,
I've been noticing that my Hero has been gulping battery down VERY fast.
In general, the battery lasts 7-8 hrs, which is not acceptable (I'm out for 12+ hrs).
My usage is not heavy. Wifi, Bluetooth and GPS are rarely, if ever, on.
I do read some news and surf the web a little but only for 2-3 of those 7-8 hrs.
Is my battery life normal?
I've been reading people achieving 12+ hours with their stock battery...
2 or 3 hours websurfing is very heavy on the battery, much more so than phone calls. One of the biggest drains is the screen and you having it on for 2 - 3 hours is going to drain the battery I guess
Seems very poor, much poorer than my iDevice that I use more frequently.
Today, after flashing the 2.1 ROM, it has gotten worse.
Battery's down to 40% in 6 hours, and Battery Usage shows 50% phone idle, 50% cell standby.
I've not even touched the phone since unplugging it 6 hours ago ;S
Is it possible I've a defective battery?
If your battery is down to 40% after 6 hours of it being idle (no screen but switched on) then either you have some power hungry app(s) running in the background or the battery is defective.
At the moment my battery is showing 40%. It was last charged about 40 hours ago, and I have had it switched on the whole time with some light use, picking up emails in the background and occassionally switching the screen on.
I ran task killer and sync was off.
One thing I didn't do was charge it for 10-13 hours straight on first charge; I just unplugged it when the led turned green in ~4 hours (impatient...).
Could this have affected battery life?
Nope - when the LED is green it is fully charged. No minimum charge times suggested in the manual.

That is amazing battery life, I never get more than 24 hours with similar use... what ROM and radio are you using Peter? Also, where are you and what network are you on?
I am in UK on Orange, and have standard Orange ROM and Radio - not the latest one but the one they had before 2.73.61.5.
I have read lots of complaints about battery life, but I think mine is fine for a smartphone. I am a relatively light user of a phone - don't do lots of surfing or watching videos. A few phone calls, very few texts, checking emails and listening to some music is all I normally do with it. The other thing I do use it for is I always have the sat nav on while I am driving, but in that case it is plugged into my Brodit mount and charging from the car.
This latest spell may have been helped because I have not been out over those 40 hours - spent the weekend at home, which means that the Hero has been logged into wifi rather than trying to use mobile data. And not used it to make calls or texts or used the music player.
I notice keep Internet connection active take a lot of battery. Go to settings and turn it off and try to see whether the problem exist. It'll will take you a few seconds to re-establish the connecting whenever you need it... not so unbearable considering it'll save a lot of battery.
Same, I notice the mobile chip is using abnormal amounts of battery.
In the morning I watched a 40 minute episode of drama.
Battery dove from 100% to 65%.
To preserve battery life, I turned Airplane mode on.
When I was done with the episode, there was still 55% battery left!
I'm pretty shocked at the battery drain.
I'm using one of the new 2.1 ROMs. They're known for having a bit of a battery-hunger. I solved it by installing the app Ultimatejuice from Market. it's a pay app, but it's worth it. It's also another app called juicedefender (free, less options) that I used before I bought the Ultimate. It also worked good! Now my battery lasts the whole day without any problem
My brother did the OTA update last night, his phone has never been rooted.
After about 5 hours today his battery has about 20% life left! Battery stats says 74% of the power was used by the display which was on for 40 minutes.
Cell standby is about 4% of battery use and he was without signal for 25% of the time, if I recall correctly.
Anyone else observing something similar?
My battery life on 2.9.2 has been less than desirable and I was considering going back to stock in hopes the battery would be better after the OTA. This is not encouraging.
Also, does he need to go through a couple battery cycles, drain fully then fully charge, before he gets a clear picture of what the battery life would be?
TIA
Yes true battery life will be clearer after a few days of use. The phone learns your usage and gives a better idea of how much charge is left.
best way is to fully charge battery and then wipe battery stats and then drain battery and then charge battery to full one charge. Then use phone normally for s couple of days. Then you will hadn't good sense of what kind of battery life you are getting.

Thanks for the response.
Am I correct that he would need to root to be able to run the battery stats script or is there another way?

I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...
I agree, the OTA froyo ED01 is worse for battery life. I get 5-8% per hour idle drain, which is way too high. I've been try to track down the issue with spare parts, system pannel, and battery details. So far I can't see any specific issue.
There are so many hoops to jump through just to get this phone working normally. It's really insanity that we should have to bust our butts on software bugs. And this isn't even mentioning the totally slow choppy ass browser in 2.2. (Vibrant browser on 2.2 SO much better)
Overall my urge to flush this POS down the toilet is growing every day.
Battery life has been pretty great on my EVO 3D using juice defender and SetCPU.
Switched to Sprint for this thing yesterday and I gotta agree. Coming from an SGS I've learned to be paranoid about my battery life, so when I barely see the battery draining off this thing I have myself convinced that it HAS to be a bug lol
How is your awake time so low compared to your up time!!
How can I see what is keeping my phone awake.

Because in the time that the phone has actually been powered on, its only been in use 4 hours. If he had been really using it, the battery would be down more than it is, but its still good battery life.
I agree, of all the devices have had so far, HERO, EVO 4G, EPIC, 3D. the 3D (comparing all of them on stock) has had the best battery life of them all. Heck even my Rooted EPIC with SFR 1.1.1 didnt get quite as good battery life, and it was rooted.
you guys know that the 3d has a larger battery than all those phones listed right?
still has the best battery i've used.
Well you will get amazing battery life turning the display brightness down anyday though. Still i have to agree this phone has great battery life. On auto my biggest battery drainer is the display but still I can get through all day with the phone. I unplugged the phone yesterday at 6 in the morning and at 9 at night I still had 20% battery life and that is with medium usage.
you barely used it. i can get great standby time too. but once i have the screen on and turn data on or a game you drop something like 10 percent an hour.
in the past 53 minutes ive had my screen on for 17 minutes. lost 8 percent.
Up Time: 37:49:30
Awake Time: 05:17:50
Battery Remaining - 52%
Impressed with battery life thus far.
I think the battery life is even better at 1.5 GHz and stock voltage.
well you guys are lucky cause my battery life stinks. medium usage, brightness at 30% sync accounts knocked back , no 4g and im getting 4-5 hours out of this thing which I think is terrible. something is wrong. Anyone else experiencing the same ?
how much of the battery is listed as "display"? last week while i was working i would leave my phone in my truck and come check on it an hour later to notice a 30%+ drop in battery. it would die after only being unplugged for 5 hours. but then i realized my screen wasn't ever turning off so if i got a text, notification, etc. that turned my screen on, my battery got drained idling in my truck.
rebooting usually fixed it but i think it was one of the early temp roots that really was causing it because i don't think it happens anymore
under battery usage the display is 75% percent of drain the rest is voice calls
mine is stock, no root here
Wow thats crazy my phone has an up time of 87 hours and an awake time of 69, i still have 95% battery left.
I'm dominating all of you.
Or maybe those two numbers mean nothing besides how long the phone has been on, and not anything to do with battery

Battery life is awesome on this phone. I still think its too good to be true. When I turn off mobile data, I can easily go a whole weekend without charging my phone. And that's with sending and receiving over a thousand texts, taking random drunken pics and vids, and talking on the phone for long periods of time. I only turn on mobile data when I need to sync up for fb, email and such or look up stuff, and I've pretty much been charging my phone every other day, and sometimes on the 3rd day. This alone makes this phone priceless to me and I've never been so satisfied with a phone like I am now.

All and all battery life on this phone is average. It lasts the same 9-10 hours as every other android i've owned. I spend the same amount of time doing the same things day in day out.
The only android I've ever noticed an exception was the NS4G and it had crazy battery life, easily 20 hours.
I think its better to post time the display or voice calls was used rather than percentage.
I'm at about 13 hrs usage with about 2hrs and 50 minutes with the display on. Probably close to 20% battery left

After the latest update I've been running some tests. A 12 hour idle drain, with the phone starting at 100% battery and WiFi off, leaves it at 24%.
In contrast, my HTC Mozart (with a smaller battery) would last nearly 3 times this.
Any ideas if this is still software screwing about, or a more fundamental problem with the Nokia?
Try reseting your phone if you have problems after update. I know it has helped some.
I had mine go from 100% to 23% over night in battery saver mode.
I removed a couple of live tiles I'd added and remembered to log out of messenger/chat, and my over night drain became sensible again.
For about a week I experience huge problem with my Z2. The battery drains like crazy. When I watch a youtube video for example it will lose at least 1% per minute. The other issue is charging. To fully charge the phone from let's say 20% to 90+% I'll need 6hrs+. Funny thing is when it's on charge and I use it it loses battery!!! I checked the power management and it turns out that the biggest consumer of battery is "Android system". It consumes around 30%. I'm prerry sure that the last time I checked the power management, before the issue, the Android system had around 8-9 consumption. I haven't installed anything that can cause such an increase, so I'm very confused.
Any help and/or explanation will be appreciated!

More info would help. What rom, what kernel. Are you rooted, do you have recovery, xposed etc? Screenshots would help also.
