Since there's no Acer Liquid mt section for now, I'll post it here
First of all, I got an Acer Liquid mt since 5 days.
The first 3 days everything went fine, since 2 days... there's a "Ghost in the Machine"
Issue 1:
The Liquid mt is swtiched on.
Battery went down to 15% - I plugged in the charger.
After 1,5 hours, the phone shows 100% (under Settings and a separate Taskbar icon, "Batteryminder").
So I took the charger off - and after 1 hour of standby the battery went down to 95%.
After 2-3 minutes of typing - 90%.
So WTF...?!
Issue 2:
So I charged again and after 15 minutes or so the phone shows 100% - again
Then I turned off the phone and charged it in off-mode.
The phone was then fully charged after another 45 minutes!
With this procedure I have normal battery life... that means 5% in around 8 hours (in standby).
Strange thing is, that the phone shows "fully charged" - when it's approximately charged 60% or so...
Does anyone have an idea?!
Thanks!
Don't worry mate this is how Lithium-ion battery's behave and I have an Acer Liquid MT it does this stuff but its not anything to worry about just don't use any battery saving programs their all crap.
First post, so hi everyone!
I bought this Galaxy Tab 2 10.1 about a year ago, it runs the original firmware with the recent Samsung update to 4.2.
Lately the battery life has become very short. This was not a gradual change, but something that seemingly happened over night. I charge the device with a travel adapter that claims to output up to 1 A. The battery monitor shows that charging works as expected and the device charges to 100 % .
In use the battery shows 100 % for a while, but after about 20 to 30 mins jumps to 4 % , giving me the low batter warning. I am travelling and the only change I can think of is, that mains power here in Canada is 110 V instead of the 220 V back home in Europe, not that I expect that to be a problem.
I don't notice the device getting warmer than usual, so I don't believe, that the battery really charges to 100 %. Is there anything on the software side I can do to investigate this further?
Thanks for any advice!

Hello everyone!
This is my second post here...but I really felt like I had to take attitude this time and actually do something.
So my samsung galaxy s3 is acting so weird that I can't use it without something bad happening for one day.
So...first of all...my battery doesn't last more than four hours straight if, for example, I am listening to music.
It literally goes down about 1% every few minutes.
Also..there is something really weird happening with my battery even after it completely shuts down. Lets's say I am on 1% and the phone shuts off. After the screen goes black and I plug it in...the charging screen appears and the battery seems to be half charged. I open the phone again and it is already at 45%. All this operation takes a matter of seconds...but still it goes from 1% to 45%. After the phone is up...this percentage starts to go down even faster than before...in the end my phone shuts down again...and this time it starts to charge from 0%.
Today it shut off...and when I got home and plugged in the charger it didn't do anything...i just left it like that for about 10 minutes then tried to power it on without the charger being plugged in...and it worked. After that it started to charge. I have no ideea what is happening.
Also...my charging time is really big. I do not know why but when I use another charger from a samsung galaxy mini 2 it seems to charge way faster.
That's pretty much all so far. If you need more details, please let me know.
I hope you can help me sort this out!
Best regards!

1.Might be the battery is dead or broken, or its not calibrated. How old is the phone and battery?
2. It seems to take ages to charge my s3 lte too, give us a number in hours how much time you need?
3. The problem where phone wont turn on or show charging when battery is as low as 1%, i had this too, i think its normal, its protecting the battery
4. Do you have overcloacked anything? It happend to me when i had ovecloaced and did benchamark test, the phone froze and battery eas 5% when i restarted the phone, but before it was 45.
Not realy helpful but i am trying XD. Also might wanna buy new battery, its not that expesive
if you are running stock rom with no rooting no anything....100% it's the battery.
if not install stock and see how it goes...if it's acting normal then the mods are the problem...if it's the same it's the battery.
Do a factory data reset on stock recovery. See how that works out first
Starting from factory reset is bad idea - it should be the last step IMHO.
First what in such case we need to check is battery health.
Percentage we see on our phone is weak indicator, because it is calculated
Better to see the voltage in different situations. How to check this (terminal app or adb in console):
cat /sys/class/power_supply/battery/voltage_now
The lowest voltage that device can handle without heavy usage is less than 3500mV (I saw even 3240mV, but with low brightness, no data connection and after trying to make a call phone turned off).
The maximum voltage is obout 4300mV.
When You see 1% of battery and voltage is realy close to 3500mV or battery is charged and voltage after removing charge is dropping realy fast to then your battery very likely need to be replaced.
I bought Samsung Extended Battery (3000mAh) and this tripled the time usage than my 2 years old normal battery 2100mAh. You can see that difference in their capacity is much smaller - about 43% biger, but give me 300% much time on battery so old one was realy worn out.
BUT if your battery wasnt used for longer than half year, you can do as follows:
1. Discharge battery
2. When phone turns off - turn it on again, but into download mode (Home-VolumeDown-Power)
3. Leave phone for as long as it turns off again and repeat step 2 till time that Download Mode wont even boot.
4. Take off battery and place it back, and again try point 2 (start Download Mode) - do it until phone will show Download Mode for only 2-3 secconds
5. Again and last time replace battery and charge phone, but turned off
6. When phone will be charged, turn it on and leave it on charger for about one hour
After those steps use your phone lightly and try to repeat whole process one more time but only when the battery will normaly discharge and phone will turn off.
I tried those steps and battery for sure can work longer FOR ONE RUN, but unfortunately it can lead to loss of capacity much faster, but it will be noticable after one year - IMHO its always good time to buy new battery.

Nothing good will come from that procedure. Those steps were useful in the epoch of nickel-cadmium batteries, where the battery had no internal circuits to monitor itself and had a tendecy to uncalibrate. Those stops would force the device and the battery to re-adapt to one another.
But now we're using Li-Ion batteries, and those DO NOT like to be fully discharged. Hell, the device might not even recognize the battery, if it has really been fully discharged.

Okay...so I went to the shop from where I bought my s3 (Orange shop) And they told me to send it to their service and I did so...as I still had it under warranty. It was there for exactly a week and today I got it back. They told me they replaced the battery (which they actually did...I checked that) and the power connector from my phone. The battery it's still not good enaugh in my opinion. Immediately after I got it back...I turned it on and it had 79% battery. In about an hour it went down about 25% (so to 54%) but I didn't used it havely (note: the mobile data option was on). I really do not know what to do. I asked someone and they told me to send it again because this is not normal.
My s3 is running stock 4.3 and used to last waay longer back in the day.
What should I do? I literally got about max 5 hours of use before I sent it and I am afraid this will happen again. I do not even want to think what is going to happen if I listen to music for example.
I turned the phone off a few hours ago...then let it charge up to 59% and then stopped because I had to leave. I used it moderately for about 4 hours and 51 minutes (as my phone says) and i have about 2h and 15minutes of screen on time. My screen is using 50% of the battery and also Android system is using about 17%...chrome 12% Android OS 7% and I think everything else is less important as they use 7%<. After those almost 5 hours...while the mobile data option was on all the time I am at 14% battery.
What do you think? Is it good enaugh? Should I send it back? I really need help!
I am waiting for suggestions.
Best regards!

I think so, the fact that you have the screen on top of Android OS (and not the other way around) pleases me. You had your screen on for 2h15m, of course your battery went down fast
Test it, charge it full, and use it. Normally.
Do this for 2 or 3 days, and check how the battery lasts
I bought my X98 Plus especially because of the promised battery life, but I am utterly disappointed. The standard scenario is the following:
- immediately after charging, the battery is draining approx. 0.7% per hour, meaning that I loose 5-7% overnight
- after even the slightest use of the tablet (browsing web, facebook, etc) standby battery drain increases to approx 5% per hour.
in reality it means that I am charging the tablet overnight, disconnecting it in the morning, browsing the news for 20 mins, putting it away (with 90+% battery remaining), and in the evening the battery is around 50-60% with the tablet being on the table untouched the whole time. if I forget to check the tablet in the evening, the next time I am touching it it has a dead battery already.
the same behaviour is present both in Widows 10, stock Android, Mirek's custom ROM and RemixOS. I have the feeling that with the original BIOS the situation was slightly better, but I have almost immediately upgraded to 3.00 (and then 3.02) so it maybe just a placebo.
Do you have any idea how could I troubleshoot the issue? I am aware that the problem is that the tablet is not entering standby/deep sleep mode, but I have no idea how to fix it, since the issue is present with fresh install of different OSs
Well bought this phone back in mid 2017,and because of sickness I haven't used it that much at all.
I charged the battery 11 times so far and was keeping the phone in a desk drawer.
A month ago I noticed that the phone won't turn on,so I plug the charger on and charged the battery to 100 %.
I supposed that the phone was on,I didn't turn it off,and the battery left to 0% and shutdown the phone.
I really can't say how long it was on 0% (suppose like maybe a month).
Today I noticed very bad battery results.
Batterylife with GSam Battery Monitor is around 12 h only.
Was the "bolded text" the reason that battery died or the reason was not using the phone for 2 years?
Is there a software to check the damage of the battery?
I installed accubattery pro but for some reason doesn't offer me Health status of battery.

I would give the battery a few full cycles to see it that sorts it or yes, the battery it would seem is on its last legs. I don't know what app to recommend as an alternative though. (My battery is 23 months old and still performs as it did when I brought the phone)
I would drain it to 5% (maybe 1%) then charge it to 100% (without using phone while charging) a few times.
Then see how it goes. Afterwards charge phone from 20% or 15%.
Ok.I will charge it to 100% and report you with results with duration time on battery and you tell me how bad is it
