Hi, I am getting a really weird pattern with my A70 battery. Basically, when I take my phone off charge at 100%, it goes down to 90% within about 20-30 mins (If that). But, it then takes at least 1-2 hours to go down from 90-80% 80-70% etc.. (Same usage pattern). I was thinking maybe a battery calibration is needed but I'm not 100% sure. Any ideas?
Not sure

I'm also facing same issue after recent software update.. Random / weird pattern with battery.
It also take random time to get full charge
I'm also thinking to do battery calibration after looking for a week

I've never seen anything like this. My battery literally dropped 6 percent in a split second while I was looking at the %. Is this a manufacturer defect, would a factory reset do anything to help? Please Help.

No, not necessarily. It takes time for a system to properly calibrate the battery. You should always give it a few full charge cycles before assuming you have a problem.

This.
I wouldn't worry about it it likely hasn't calibrated yet, I've seen many of my devices do this, especially new or freshly wiped

You are overreacting. Large amount of power consumption in short time isn't unheard of. For example, it has been reported that phone searching for connections and syncing everything at once can cause large drops in battery meter. And battery meter isn't always accurate anyway.
If the battery drops more drastically and happens more than a couple of times, then I would worry.
My tablet does the same too it either goes from 78 to 76 or just skips from 30 to 26 randomly
The first day I got it, the battery went from ~50 to ~60. You read that right...it went up without charging. Just let the battery settle and it will become perfectly normal again.
Mine does the same, drop from 33% to 23% instantly. and while charging, it jumps from 94% to 100% too. But i do get 9:30 hrs use time with Chrome.
Still in the return period window, not sure to return it or not.
I think that the battery percentage sometimes freezes and doesnt update right. So once the software finally gets a good reading or update it will suddenly change alot. I had it stay at 85% for like 3 hours and was thinging, AWESOME this is amazing, then 15 minutes later it was at 50% and i was like, oh, damn it was just playing mind games with me.
The battery gauge doesn't really 'know' the charge state of the battery, it's just guessing more or less accurately based on a model of the battery.
It takes things like battery voltage, load, temperature, voltage change with varying load (to estimate internal resistance of the battery) to basically make an 'educated' guess of the charge state. There can be pretty big corrections of that guess - a 10% jump is very normal. It doesn't mean the battery charge state has changed, it just means the battery gauge has corrected it's estimate.
during charging, i seen that it increased 1% per every 4~6 mins from 1% to 94%, then it jumped to 100% from 94% in the next 6 mins.
It also skipped percentage 4~6 times while charging from 1% to 94%, 1% per skip.
I used Batterybot pro to monitor the battery, it will logs when the percentage has changed, that's how i know it was doing this.
I've been experiencing huge battery drops (from 10% up to 20%) after I reboot my phone. Is this a KitKat issue or is it my battery?
In the morning from 99% (after checking a few messages in the morning), I rebooted and I dropped 11% to 88%.
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one. :good:
I didnt found it on reboots, but i have this problem when i enter recovery. 20 minutes in recovery - i dont hace 20% of battery.

Hmmm that's strange.
I've noticed it usually drops more when I leave my headphones in.
full loaded ACE 2.
reboot cost u 5%
first 10 % gone in a few minutes for heavy users and in a few hours when deepsleep !!
what i wanna say.
the first 10 % gone in a few.
after that normal drain.
I often get this, although not as bad. I usually lose 2-5% on a reboot, sometimes up to 10%. The other week I charged it to 100% when it was off, turned it on and had 92%.
so is this actually a problem or is it normal for everyone?. Mine looses 5-8% in the first couple of minutes after I unplug the charger..
It's normal.

Same experience. Around 5% to 10% is lost during my reboots.

Its normal. I usually lose the first 5% of a full charge in a couple of minutes. After it gets to 95%, battery charge will drain normally depending on usage.

ok then, thanks...I just thought that this didn;t happen when I was on GB, but it doesn;t matter anyway..
If I reboot once, I will lose between 5 - 10% battery. However, if I reboot straight after the first reboot, I will lose between 0 - 2% battery. I've never really understood this.

Phone need more energy for reboot, that causing the drain. Mine usually drop 2-5%. After recharge battery alsi drop to 95-92% fast. Thats normal

Battery Charging Issue
Is this normal?
When I charge my battery whether it be from mains or USB computer it charges ok, but as soon as it gets to 100% it still says charging for a little time and doesn't report the unplug charger message right away.
With the Jellybean 4.1.2 system I don't get the alert tone when the battery reaches FULL, therefore I have a feeling that when it still says charging even though it's showing 100% that it's actually decreasing power at that point, any help please?
I have tried other batteries, and one in particular goes from 90% right up to 100% and seems to miss that last 10 percent, so I don't use that one now.
I have the most current firmware installed.
Buy a new one

when it says 100%, you still have to wait for a few minutes before it displays the green "full" icon in the upper left corner and asks you to disconnect the charger.
However, the first 5-8% always drains REALLY fast and not proportionally to the rest of the battery drain...
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one.

what about the initial drain? does the first 10% still drop fast or has this changed too with the new battery?
I just wish that JellyBean 4.1.2 would give an alert sound when the battery has reached it's full limit like Gingerbread used to do.
Who would be the best place to ask them to do this on their next update?
But I think that it does..a very short one indeed, but it does, along with the screen lighting up briefly..

Doesn't make a sound on my phone and im not always looking at my phone to see it light up.
I have sounds all turned on and on full volume so no reason why I dont hear a sound when its reached full capacity.

are you using custom battery ? like double-powered-battery
Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.
In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!
It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.
What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?
BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)
Hi everyone,
I bought the phone on December from Gearbest and I have some issues. First of all the most important one, battery. For some days I've been noticing a very strange behavior, the battery might seem charged at 100% but may turn off at 60%. Also noticed that while charging it goes from 7% to about 34% within half an hour or less, then suddenly goes up to about 60%. I can't be sure anymore if the phone will last when I'm out. Also, sometimes when entering the battery menu, it says it has no available battery data and the diagram only shows it's current battery percent. What can I do to determine if it's an issue with the battery or the charger? Is there a way to calibrate the battery?
Secondly, the fingerprint issue I've had since day 1 but I thought it might be a software problem that an update would fix but that didn't help. I've never added a fingerprint because at the "add a finger" screen the graphic appears but won't recognise any move, after a bit the whole screen freezes and I push the home button to go back.
Any suggestions? I was so unlucky with this order and it was my first Chinese phone...next time I think I'll stick to the large brands...
I've a brand new Xiaomi Mi 10T Lite, but since a few days I notice that it seems that the battery is draining fast.
So I've done a test: I've charged my phone to 100% and used it until it turned off due to too low battery and it lasted 23 hours and 3 minutes.
But I doubt if this is normal and I'm kinda worried about it.
I've bluetooth off, and wifi is always on except when I go outside and then I use mobile data.
I use my phone for surfing, using social media, chatting, gaming, making nice pics and more.
So is the battery life normal or is this a serious problem?
is 23hr bad ? I feel like my one is always above 80% as it charges that fast I don't seem to notice the battery being low

I dunno
I haven't mentioned the standby time and the active time in the topic, and I cannot find that data anymore so that means I have to do the test again
I would advise to install AccuBattery app, fully charge the phone and look at screen off and screen on power consumption at the end of the day.
These numbers are "normal":
Screen off - no activity (over night or phone just laying down for a few hours): 0.2-0.3%/h
Screen off - the usual daily activity (moving around with the phone in the pocket, Whatsapp for web active, Google location tracking active etc.): up to 1.3%/h
Screen on - about 7-9%/h
I'll do another test on Friday as I said.
I'll charge the phone to 100% and use it until the phone turns itself off due to low battery and look at the active time then.
I'll post the results here if the test is done.
What were the results?

I'll tell it you once I've the results.
Today I've redone the test.
I charged my phone to 100% and I then I used it until it was 5%.
I got an active time of 5 hours and 27 minutes and the standby time is 18 hours and 1 minute

My phone is pretty new and I am using it more frequently these days. This leads to similar battery times like you describe them.
I did not do the exact same discharging like you did, but imo battery drains mainly during screen-on time. Over night it is quite stable and only slowly discharging.
Maybe power consumption is dominated by the LED screen? This might be the reason why Xiaomi has such an aggressive screen dimming implemented...
I think what _mysiak_ is describing above, is pretty accurate and explains what you are observing.

Unless your trying to calibrate the battery that's really stressful to the battery to use it like that.
Puts a lot of wear on it... fast.

I know that, and I used to do that all the time but when I received my new phone I changed my habits.
I'm now trying to keep my battery level between 90% and 40% or 30%.

I go with a maximum 80% cutoff.
My current target range is 45-72%
