whenever i connect my 0% battery z1 to power supply, it behaves strangly sometimes, like no red illumination, which indicate no charging(press power button nothing shows on screen). or, red illumination but u press the power button to check how much the battery has been charged & screen remains black. disconnecting phone to power supply & reconnecting works sometimes only. it is still new, bought during christmas, but it freaks me out now.
Try to do a factory reset. If that didn't work take it to Sony service center while it's still under warranty.

Mine too I think!

Why would u even let your phone to be at 0% battery?!
I never let mine to go inder 14% coz it's very bad for the battery to be totally dischaged!

It's better to get it to 0% once in a mother (or less/more).
Are you using the charger and USB cable that was provided with Z1? I recently discovered that not all charging adapters and cables are made equal, and some cables don't provide enough current to charge certain devices.

This is not true, you will actually decrease the life of your battery by doing this. The XZ1 uses a Li-on battery chemistry.

Li-on batteries are well known for being problematic at low levels of charge (can't recharge, decrease in life, etc).
Lithium ion chemistry prefers partial discharge to deep discharge, so it's best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a "memory", you do not harm the battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it's ruined.

A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.

Hopefully, the power management circuitry will prevent anyone from reaching the "ruined" voltage levels, but I've already seen quite a few people posting about phones which aren't turning back on after running them down to 0%. Both of those links provide good information on preserving Li-on battery life.
If you like your phone, don't discharge below 10% and let the phone nurse on a charger often.
@xasbo You actually get the battery to 0% once a month (more/less) to keep the battery calibrated as flashing ROMs changes battery calibration.
All my previous phones (Xperia play, Xperia go, Xperia Z, and now Z1) went to 0% and then 100% more than once with no problem at all. (Z1 only once so far)

You can do what you like, but you will not escape the physical chemistry of the battery. Full discharges are bad for the health of the battery.
thanks guys~
well does this have something to do with made in china? samsungs have no such problems. my old phone, xperia sola has no such problem too

Doubt it. Maybe a design problem. Either way, you shouldn't discharge that battery that far.

New battery was drained and fully charged while the phone was off.
Now it drains to 15% after less then 12 hours of average use.
When charger is unplugged the battery imm goes down to 97%
what is the best way to improve the battery performance ?
Don't use it as much
Everything has a work in time, your phone needs to forget about old battery and dance with a new partner. Give it a chance...
Oh and search is a good thing. This phone isn't cutting edge anymore.

Did you get this battery from china?
It probably has like 800mah.
Is there any battery today that does not originate in China ?
It is marked "SAMSUNG G7 1500mah".
I already tried to calibrate the battery about a week ago using a market application that claims to perform a reset of the battery stats.
after the reset I drained the battery for 3 days and recharged while the phone was off every night (during those 3 days).
then for the first few days the battery actually held up nicely reaching 50-60% after 12 hours.
after a week or so it started to drain more rapidly reaching 15-20% in the evening.
It also fails to hold 100% when the charger is unplugged, going straight to 97%.
should I try another battery or is there a another way to calibrate the battery ?

Is there a way to identify a genuine non-fake G7 battery ?
That's how mine looks. My battery does seem to drain fast when I am actually using it. But, also when I'm not using it, it seems to keep at a steady battery level for a while. I guess it's a trade off. I also use Juice Defender which definitely helps.
I probably used juice defender for about 4 months. Then I tried running without it and found I got equal or better battery life.
Hi,
I've had a Nexus 6 for some days now, and its battery life doesn't seem too good. I'm used to leave my phone overnight and wake up to it having over 90% battery left, but with the N6 it usually has a little over 80. Today it had 83%, and after browsing the web for some minutes (maybe 10 or 15) it's down to 75%... That's almost 1% a minute, which seems a lot to me.
If I take a look at the battery screen, I see this:

If I'm not mistaken, something seems to have kept the phone awake during the night. Is that right? I'm using M preview 2, could that be causing the problem? Is the phone defective? What could be wrong here?
Thanks in advance for your help.
PS. Battery life is at 71%... That's 4% down since I wrote that part above. This thing drains so fast it's scary.
It could be anything from the ROM itself to a Rouge app. I would flash back to bone stock and see what you get over a few days with a couple charge cycles. And then compare with another ROM.

Yes the andoird m preview 2 is not showing battery stats correctly. You will probably notice that once your phone goes down to 1% it could stay there for an hour or so. Just be sure to run the phone to complete 0%. Then charge to 100% and leave for about an hour after that. That should recalibrate it after a few cycles. It is a widespread "issue" with the m preview 2.

why dont you keep it on the charger overnight, that way itll be at 100% for you??? it does not hurt the phone, at all.

i use the turbo charger. but it doesnt matter. if you watch the voltage going in, it get drastically reduced above 92%, and again at like 97%. and when the device actually stops charging, its at 0% voltage going in. btw, most times it does not stop charging at 100%. that happens anywhere from 5 minutes to 30 minutes after hitting 100%. thats because our battery % is slightly off.
I have been using quick charger to charger my N6 since I got this phone in 12/2014. I had no problem until recently my phone will power off itself when its battery gets to 15%. Before, 15%of better life will lasts me another 15-30 mins. I charges 2-3 times a day using quick charger and I think it's killing the battery!!! Anyone had similar issue?

and what evidence do you have thst the quick charger is "killing the battery"? i mean wheres your proof? i think doesnt prove anything. your battery stats just need to ne recalibrated.
How do I recalibrate?
Dude... Your battery is almost 1 year old... It's normal for the battery to start going weird with normal use between a year and 18 months however, you charging the phone 2 to 3 times a day isn't great and is likely a cause for your issue... I charge mine once a day.
There is a thread somewhere here in The N6 forum to possibly fix your issue.

lol, no. thats a battery stat, and ive seen them much wierder than yours. that has no evidence that charging using the default supplied charger is destroying your battery. but.. it might show that you have an issue, just not the issue that you think it is.

I'm just trying to figure out what happened. I know you said about battery calibration; but why my phone dies at 30%? I think I might need a replacement!
Its a nexus 6 thing, the internal power supply hardware for this phone is cheap and "just enough" to power the phone. When the voltage on the battery drops from being drained the cpu shuts down as a fail safe, the 5.1 update "fixed" the issue by underclocking the cpu and gpu at 40% battery (iirc) and unplugging cores at <20%. Many custom kernels remove this for performance boosting but then some phones run into the power supply issues usually in the lower binned chips (ones with higher voltage tables). Age likely doesn't help anything and a quick charge probably doesn't either. There's a big post about it on the zen kernel thread.
It's more of a Nexus thing. My N7 2013 does this all the time. Happened only a few months after release. Download an app called Battery Calibrator. Can't remember if I got it from here or from the PlayStore. It requires root access.
So.....are you on a custom rom or stock? If custom rom there's your problem right there, check for an update. If on stock also make sure your on the latest build. If all else fails do a factory reset. If problems persists just put in a warranty claim with Motorola.
Can someone help me, Im having a battery drain on my lenovo a7000-a,
I already bought 2 Batteries and change roms, but still my battery keep draining and Ive already tried all those calibrate methods around the internet.
From 100% down to around 80-60% is fine, but when it reaches around 60% below, my battery starts draining for like -1% every 30 secs.
Tried different roms and a few apps running.
40% 1:07am down to 1% at 1:14am

Lol welcome to the club.
The battery drain is a classic feature of MTK chipsets and that's a reason why people don't prefer MTK here at xda.
The drain can't be fixed. The kernel sources seem messed up by mtk and unfortunately even though I'm the only one who reached to extreme depths in mtk source in this forum, I couldn't find a solution. Maybe it's just a hardware level issue. Maybe it's an issue with the chip's design itself. One thing I found out was that though we can't fix the drain, we can move it to different parts of battery %. Like you can drop the 20% right at max 100% but keep the rest 80% fine. Or, as by default, you get a drop from around 30-35 upto 15-10%.
I hope I made it clear enough

Nope, I don't think so. During the last few battery % it lasts suspiciously too long, and after the phone dies, you can reboot it and still find 12% battery suddenly come up.
So I think it is actually a bug and a serious one
I purchased this about a month ago. I have been reading a lot of posts out here about people having fairly low battery life. So I had installed Accubattery to see if the discharge is abnormal. I checked today and it seems like Accubattery is claiming that my battery is only at 50~% health. Now I am unsure that if this is because it is a genuine fault or because this phone is supposed to have 2 2500mAh batteries and Accubattery is detecting only one of them. Any idea about this?

Those SOT numbers seem erratic. Some reasonable, others look impossible.
When you're using the browser not watching vids the usage should low.
As the previous poster mentioned it may just not have good sensing for battery usage.
Accubattery is only as good as the data it's getting. Even then it can screw up. I don't understand what's going on there.
Rather strange. I don't have that phone so I don't know what it's nominal run time should be. If it's running cool and you can get 8-10 hours SOT you're probably in the ball park.

Hmmm, okay. I'll continue observing my phone's behaviour then. I do get over 8-10 hours SOT on medium usage. Additionally, I read from other threads that the 120W charger isn't charging the phone fully and it makes sense to charge with a lower power charger. So I will try that as well. Will keep this thread updated if I see any improvements.
Accubattery doesn't work well with dual battery setup, that's why it's showing Battery health at 47%.
Set design capacity to 2500.
11T PRO has 2x 2500mah battery for ultra fast charging. Set the design capacity to 2500 and you will be fine.

This presents a potential problem in the future as one battery can degrade and fail independently of the other. You really need to be able to monitoring both.
If the manufacturer designed it properly each battery should have its own power controller in a perfect world. Not sure if this is so on any of the dual battery phones...
