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

Am I the only one who thinks that this is a way to make the battery capacity seem bigger/phone lasting longer? That its not a bug but rather a "feature" for manufacturer to make buyers think that phone has better battery than it actually has ?

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

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 ?

Its still quite possibly a fake samsung battery. Did it come from a reputable seller at least? If yes return it.

Hey BenKranged
What APP did you use for that screen capture? I know this has nothing to do with this post but looking for one on the market and there are so many to choose from.

I've had good luck with the ShootMe app. (Sorry, I'm not BenKranged, but I thought I'd throw that out there.)

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.
Anyone felt like returning this phones after a week cause of battery life?
Im not cause its not that bad and maybe a custom ROM may be able to work on that just looking for other people's experience and what they think thanks!
It's useable with a few temp.. tweaks .
The bottom line is this all occurs with lollipop in general S5 was great on kitkat ...until 5.0
It's not the phone it's features and O.S
People are disabling Volte and WiFi calling it helps a lot
I wouldn't return it over battery life yet the camera is way to good
Give it time We get roms soon and mods it's I take back everything +I said
Samsung needs to take back every s6 and Rethink there whole O.S
For a 750$ flag ship release its so buggy it's hopeless .
Camera is only worthwhile feature

Do one factory reset and set up phone again and disable VOLTE FOR NOW under Phone /More .
Cycle the battery meaning charge filly and let it fully drain as far as you can before recharging again .Another words don't fully charge it when it hits 40%
This is true the battery's learn a drain span
I'f you recharge anything above 10% it isn't gonna learn it's max capacity Takes like a week.
The main fix is Volte disable and WiFi calling
Sent from my SM-G920T using XDA Free mobile app
i turned off volte i dont really see the need for it i mean its a phone call why do you need such high speeds lol my phone is at 2 percent waiting for it to die lol thanks
If it wasn't for the rapid quick charge I probably would have
returned it but the fact that I can top off in a half an hour it's really not a problem getting through the day.
I think it has something to do that the phone is not going to deep sleep, i rooted mine and flashed a custom kernel, now it does deep sleep and battery is ok now
While battery life isn't as good as some phones I've used recently I still got 5hrs SOT yesterday. Not bad at all.

That is pretty good for this phone ....
Has anyone tried going into Developer Options }Limit Back
Ground Processes to 4 ?
I wonder if this barely slows the Phone for most things but might give an additional ( wild guess 10% to 25%) Battery Life.
I don't have one but if this works....be easier for me to decide.
I may put this idea in a separate Thread.

Yea I can't complain about battery life. The screen is so ridiculous I end up using the phone for no reason, so my usage at least for now since it's new, isn't my normal usage.

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.
Hello everybody! I own a Huawei P9 running Eva-L19 version. And using whatever root app inside my phone, they all shows that my phone has a 2900maH battery. What seems weird is that on every site, GSMArena etc. they all say that Huawei P9 has got a 3000maH battery. Few months ago I've dropped my phone and crack the screen and went into factory, I'm thinking would it be that my battery has been changed...? I don't remember what is the battery capacity showed before it went into factory, thats the problem! It would be kind for anyone to confirm with me what's their battery capacity. Thanksss

Normally wiping battery stats dont do anything in newer devices/android versions(in terms of making battery last longer), but you can try turning off phone, charge it to full and wipe battery stats. Maybe battery was disconnected and phone dont see it properly(but I doubt it... )
As for my phone Its 3000maH on all apps that check it.

Its just a number on some apps. It would be sad if your battery life would be worst than normal. Its imposible to say how long battery will last because everyone use phones differently, they have different apps working in background and features enabled/disabled but no matter of OS version average should be two days before battery on P9 reach 5%
And taht is with LTE turned off(that is one of most power hungry feature in every phone. Tip: just dont use it, HSPA is enough to stream even 1080 videos)
I normally have 40% at the end of the day because I have Gear Fit synced and I use NFC and GPS all the time, but even if phone would have 2900mah battery difference should be not bigger than 5% So dont worry about it that much.

Thanks a lot! Will try and monitor how my phone behaves this few weeks. But yeah, since its just 100mah, guess I'll just sleep with it
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?

I've had my 11T Pro for roughly two weeks and I have the same issue.
It doesn't read charging speed correctly which confuses it's health calculations.
I'm sure your phone is fine.

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...
