I'm trying to nail down if this is normal behavior or not my phone always shutdowns itself when the battery level goes below 7%, no matter what.
then I turn it on it boots and shows 0% of battery left then it shutdown again, next time I try it's totally dead.
Tried with a battery calibration improved the overall battery life but that mark is still there.
Is that normal? I mean when I used to have a G1 it lasted until 1% or so.. 7% can be very well an extra hour of usage that I'm loosing.

I've noticed the same thing. It'll be interesting to see if anyone has a solution.
7% of battery life is just a number. It could very well be inaccurate, and simply reporting 7% when you actually have 0%. When you reboot and it shows 0% just backs this idea up. You are not "losing" an hour of battery life, you simply never had it.
To check this, use spare parts to look at the voltage of your battery when it approaches 7%.
Also, this belongs in the QA section.
I'll give it a try, interesting is the fact that both Cyanogen RC3 and Battery Monitor are reporting the same thing.
Will keep an eye on the voltage, what should it say ? something near 0?
seriously?
AFAIK li-on battery never be below 5% or 7% why?
because if you get below of this the battery will be dead and will not work anymore. so thats normal.

I've also read its normal but if its normal why isn't it calibrated to show 0% when its actually at 7%? My phone goes off at ~10%
btw there are so many battery threads lately.. http://forum.xda-developers.com/showthread.php?t=702167
Yeh, mine also goes off at around 10%.
it seems normal then , time to get myself a spare battery ... travel can be painful if no power outlet / usb port is near me
Yes its kinda normal. My phone has always shut down at 8% from day 1. I think its because of what we're talking about in the battery cal thread personally.
I have had my Galaxy S for a bit over a week now and am pretty disappointed with the battery performance. Most days I take my battery off the charger at 7am and it reaches 15% low battery warning by 1-2pm. I do spend a fair amount of time reading XDA and listening to music. I'm currently running Stock JM1 firmware with no lagfixes.
Here's a list of my apps that I have installed:
http://www.appbrain.com/user/Lokhor/apps-on-the-samsung-galaxy-s
I am running JuiceDefender which I thought would make a big difference and does not. I have also set Tasker to change the Brightness level to 20 (below the safety threshold) when the battery reaches 50% or below, otherwise the brightness is at the minimum (30%).
I have heard that you need to condition the battery so I have been trying to do this but it doesn't seem to have had much effect. Today I used my phone only casually and it's currently at 22% after 12.5 hours. The battery use details show the following:
Display at 56% being on for 2h22m and 13s.
Cell Standby 18% Time on 9h21m, time without signal 13%
Phone Idle 7% Time on 7h33m
Android System 5% CPU usage 23m39s CPU foreground 24s
Android OS 3% CPU Usage 13m 27s
Is this normal? Is there anything I'm doing wrong?
Please help
I don't know what others are telling you about conditioning a LiIon battery but you don't have to. LiIon batteries don't suffer from what NiCad do. Some do suggest wearing the battery down to nil and then charging it up again. However, this is pretty bad for the battery and should not be done more than once every 30 cycles. With every LiIon battery I've ever owned I've either trickle charged it or charged it when it wasn't too low and they've all lasted over 3 years. I've never conditioned one.
Anyway, my advice to you is to see how long your battery lasts in standby. Mine could probably last 3 days or more if I don't bother it too much (with sync, wifi and all that good stuff). I find the worst contender for battery drain is the display. The only problem I see with your stats there is that I've played Asphalt5 for around an hour and a half which is quite heavy on juice and it only drains roughly 10%-15%. Then again you're browsing the web so maybe probably worse.
Oh, and when charging your phone, don't use the USB hooked up to a computer as it doesn't stop charging when it's full. Use the wall charger to charge.
no need to worry more

I found that charging it whenever it was convenient instead of when it was low would result in a charge that lasted ~24 hours.
I've noticed significant increase in battery life since I started waiting for the 15% charge warning, plugging it in till it was full and then unplugging it. I get 2-3 days of use this way.
I also set my email to only sync between 6 AM and 11 PM. I believe this helps a lot as well.
since we are about this topic, check this out
How to spot fake battery vs. OEM battery: http://forum.xda-developers.com/showthread.php?p=7953322
so if I'm listening to music during the day at work should I have my phone plugged into the wall charger or just let the battery run down?
Last night I took the charger off at midnight when it was full and when I woke up it had only dropped 5%. After reading my emails quickly it was at 93%.
it works fine either way

I find leaving the brightness on automatic uses up loads of battery. Setting it to lowest seems to make the phone last 24hrs+
I also found that having beautiful widgets clock/weather installed used up a lot of battery for some reason.
I don't use weather because it has to sync every so often to update it which to me is a waste...I'll just look outside. I also leave brightness on the lowest setting wherever I am as the screen is already very bright (why waste battery?).
My experiences with my SGS have taught me to be conservative with its battery. Anytime you turn the screen on, you eat power like crazy. The best bet is to just top her off whenever the need arises. Personally, I have found that I'm fine just topping her off in the car when I'm driving, so that I start my work day at high 90's, and especially once I've got my morning browsing out of the way, I don't eat a big chunk of battery at any other time.
But yes, if you find you are running low, you can happily just take a half hour to charge from a USB port to give you an extra boost. Alternatively, spare batteries and so forth do the same thing, although it can be annoying if you don't have a charger that will do the phone and a spare battery at once.
im experimenting with apndroid now to turn of 3g then i dont specifacly need it. It comes with an on/off widget. Looks promising so far. 40% at 2300 hour and then i have used wifi a bit, played angry birds and talked for about 2 hours in total.
I got a full stock N7 16GB 4.2 OTA which I'm not planning to root or flash (that's what my One X is for =P).
I noticed that quite often if I leave my N7 for a night with about 40% battery life, in the morning it will fully shut down with about 14% battery life remaining. Checking battery usage I see a sharp, almost vertical drop. Something's destroying battery when it gets about half way.
Anybody else had this issue?
Screenshot attached.
Try and fully discharge and charge it a couple of times. The battery may be poorly calibrated. U can use a battery drainer if you are impatient. https://play.google.com/store/search?q=battery+drainer&c=apps

I don't know which update it was put in but it seems Google have added something that shuts down the N7 automatically at 20% to save the battery. I don't know if this is for every unit or not but it's been doing it for me and a few friends who have them too. I guess this is to save the battery as it can affect the recharging efficiency and the battery will die faster than normal if you allow it to drain further.
From your picture it looks like it's doing as it should, shutting down at about 20%, and then guestimating the battery stats, which fools the reading. However dropping from 40% to 20% overnight sounds like you have one or more rogue apps installed causing some serious drain, unless it's something you know/want to be running of course.
According to the Battery thread in this forum, some people experience a high overnight battery drain, and some get a low one.
I am currently a member of the high club. For battery testing, I have most things turned off, like location services and google now. Last night overnight drain (8 hours) took the battery from 76% to 58%... 18%. On my previous phone, the HTC One, the overnight drain would be around 6%.
I am curious about the people who are getting low (~5%) overnight drains. Do they all have Wifi off? What is their secret?! Do tell.

Install better battery stats to monitor what's going on. I think the one night I left it off charge over night I lost maybe 6-8% but I slept for like 10+ hours. This is with google now on, gps on, wifi on.
What i'm testing now that I think will actually improve batt life is having wifi turn off when display is off (unless plugged in). I think I noticed less idle drain at home when I did this but it was temporary. Giving it a shot over a few days now.
I leave wifi on and I get less than 5% drain. Nothing syncs when my screen is off except notification weather pro every two hours and Yahoo weather

Personally I think the X and new droids have idle drain issues. Even when better battery stats shows nearly 100% deep sleep overnight, I still lose 8-10%. In comparison, on my HTC One mini, which is setup EXACTLY the same as my X in terms of installed apps, syncing accounts, running services, etc., I lose only 2-3% overnight. The number of people complaining about the issue seems to confirm it is more widespread than on other recent phones, as do the countless screenshots showing unusually high android OS usage in battery stats.

I honestly believe it will be patched with the Camera.
I'm having the same issue. People are reporting crazy battery stats with like 20+ hours of use 2+ hours of screen on and like 20% battery left. I get MAYBE 12 hours of use and 2 hours of screen on and 20-25% left. My mediaserver is keeping the phone awake for almost an hour+ each day, and without root I can't figure out how to stop it. I always have GPS/Google Now/Bluetooth off, too.
I thought the drain was related to Wifi. But last night WiFi was turned off for the night and I still got 18% battery drain in about 8 hours.
Wifi at home and overnight. I get about 5% drain... however, the wifi at work kills my phones battery with the wlan wakelock.
Maybe there is something going on with the X and certain wifi networks?

Interesting theory but my overnight idle drain was approximately the same on both LTE and WiFi. 10-15%.

How about turning off all radios (flight mode) and observe battery drain at night. Then turning wifi while on flight mode the next night and see the battery drain and so on until you can pin point what causes the most drain.

Hi All
I bought Nokia 7 Plus yesterday and set it up, but the battery drain so fast. I left my phone to sleep with wifi on throughout my sleep it drains 10% with just pushing notifications from FB, like everytime I will get FB Notifications and not open it it will drain 1% of the battery.
Remove fb and see magic
U just answered to your question. It's not the phone, it's just crappy facebook app.
Facebook Lite is the way to go if you need FB, I think - normal version eats battery a lot, and I'm not sure if that will be fixed at all - seems like they don't care.
If you have to use Facebook, use Facebook lite or alternative apps like Friendly.
Hi, I got Nokia 7 Plus yesterday and started using it today. Initially with the battery percentage came with package, battery draining was slow. After doing first charging from 21% to 100%, battery is draining too fast. It is common for some batteries and takes some charging cycles to get battery optimized. If battery draining is happening too fast even after 3 to 5 charging cycles then there would be some fault with battery.

I got my phone day before yesterday & its now running Android 8.1 with the May security patch. Since the time of use, I've charged my phone only twice & both times charged it up to 100%. I feel the batter is draining. Please have a look at the screenshots and let me know if the battery consumption is fine or its draining fast. The battery dropped by 1% in 4 mins of the phone being idle with the display closed. Also the stock camera app is consuming a lot of battery.
I can confirm a very hard drain, too. No way to reach 7-10 hours of usage.
i'm getting about 5-5.5 hours of sot with moderate usage... Checked the app usage..where it shows PUBG used 12% battery in 38 min, 45 min of youtube drain 8% 26min Instagram drain 5%...I don't use fb much on phone when needed i mainly use fb lite... .i don't use auto brightness. so my brightness level is always 45%.. in overnight( well it's like 5-6 hours) battery percentage dropped 4%.. Wifi is always on and GPS is always on high accuracy.. in power saver 19 apps are allowed for background activity...
Battery drain
I just purchased my phone yesterday and used it for some time. I put it on charging at around 20% and didn't use it until full charge. After it got completely charged and then I just used it for few mins it went down 100% to 95% very fast; later after few mins I started suffering net and did misc stuff for about an hour it went down to 85%. Next morning I saw the battery % was 81%. Is this normal? I mean how can it last for 2 day as the company claimed. Aslo I am android 8.1.0

This has been a comman issue with Nokia 7 plus, including me. My battery had high discharge rates in both Oreo and Pie. However, post March security update, I am seeing some good battery life. I would also suggest to update to Pie and update Device Health from Play Store. Hope it works out for you.
try letting the battery drain to 0% then charging it to 100
TA1062 with build 00WW_3_51F here.
Before the march update, the phone could last for almost 2 days with moderate usage.
After the march update, I barely have 5 hours of standby time, and like 2 hour of usage time. This is crazy ! Not heating, but also randomly shuts down while it says like 65% remaining battery. I haven't changed anything else !!!
Does anyone have any idea how to improve this ?
