[Q] Shocking Battery Life - Nokia Lumia 800

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.

Battery Drain

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

Battery life suddenly improved A LOT

I got my refurb LG Optimus from T-mobile a little over two weeks ago. I set it up with Groove IP and have wifi on almost all day with the phone in airplane mode. Running stock 2.2 and stock kernel, haven't rooted or anything. Generally I had it unplugged for about 14 hours a day and would charge it nightly. Battery life would get down in the 20-30% range on occasion and it was generally looking like I would have gotten about 20 hours total if I would have taken it down to 0%.
Without remembering making any major changes (updated a couple apps maybe) I am currently at 2 days 4 hours since last charge and battery is at 60%. This is the first time it's going this long ... basically two nights ago I was about to plug it in when I noticed the battery level was still really high so I didn't bother. Still high last night so I again didn't plug it in.
Any ideas what would cause this to happen? Looking at the battery use, it is mostly the same as before (50% wifi, 19% phone idle, 15% cell standby, 10% android system, a little to display and some other stuff). Was the battery level indication just wrong the first couple weeks? i.e. when it said 30% left it really might have been at like 80%?
Not complaining at all of course and I hope I keep getting this battery life.

battery information problem

hi guys , i got some problem with the information displayed for my razr maxx. the thing is the battery usage curve won't change for the first 10% of power drain, and the awake bar and screen on bar are full. but when the battery drops to 80% and below, the curve starts to count from the 80% position, what is going on? how can i fix it ?
here is the screenshot
How many times have you already charged that battery from 0% to 100% and drained it back again to 0%?
Seems like a simple calibration issue that should have no effect in real world battery performance.
Had that too. If you want to know more about this, look up "batterystats.bin".
So, if you haven't done what I said in the first line, do it and report back.
i have tried delete the .bin file bwfore, nothing changed. i think i will try to charge it from 0to 100again see if there will be any change. btw will the battery calibration apps solve this?

Read that. You don't have to do anything, just let your razr get some charge cycles and the readouts will be right. Remember: There is no need to tinker with this, as this has no effect except for cosmetic terms.
thanks for the information. one more thing, the battery indicator always shows that the screen on and awake time are the same, even after i turn off the screen and play music for an hour. is this normal? or the system keeps recognizing the status of the screen as on? how should i deal with this?
I would just wait a few days (read: charge cycles) and look again. Indeed strange, but if your battery doesn't get drained this also seems just to be another cosmetic issue.
actually it seems it has been more energy draining than before. it wouldn't drop 1% when i turned on flight mode at night and checked it in the morning. but now even i turn on flight mode it drops about 5% next morning.

Don't count on the battery percentage today. Look again tomorrow/after some charge cycles.
The battery readouts need to be calibrated to display the correct battery level.
I had the same "issues" (in fact, those don't seem to be real issues) and they went away. I assume your razr will behave the same as mine
Is the phone still new? I know mine was a little wonky until the charging and the meter apparently calibrated themselves to Maxx's battery Ever since, it's been very accurate.
yes it is still new. i got it about half a month ago. just got it charged to 100% from 0%. gonna see what will happen。

Poor Battery Life on Captivate Running 4.0.4

I have a Captivate running Dark Knight's 4.0.4 and the battery life I get is very poor. Usually it says that Android OS or Google Services is taking about 30, 40+ percent in battery life. I get about only 10 hours of use with the device, and i still get battery drain even when it is in sleep. I've checked better battery stats and gtalk_async_conn has been waking up the device. I disabled all syncing, and in the Play Store disabled automatic checking for updates. I've tried calibrating my battery also but nothing, mainly since the phone cant turn on for some reason while it is charging. But no matter what I do, that process is still killing my battery. Does anyone know how to fix this? I had the phone off and charging for 12 hours, and 1 hour has past since i turned it on, using the phone for about 3 minutes, and the rest of the time it was in sleep, and the battery is down to 91%. Please Help!

[Q] Atrix Battery Drain Issue

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.

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.
