Recently I bought a Meizu M2 mini and from the first day I have a small problem with the battery. When the battery reaches 20% suddenly within a minute drops to 1%.I received the phone with 184.108.40.206U version and upgrate to 220.127.116.11U version to solve the problem but nothing.I try the 18.104.22.168A version but the problem exists.Also I try to calibrate the battery but nothing.I contact with the store which I bought ot and told me to flash 4.5.3A version.I install 4.5.3A and ididn’t see difference…Can you help me ???
@soupis This is weird, where did you buy the phone from? And what apps do you have running in background?
How many charge cycles, did you give the battery to calibrate itself?
In theory it doesn’t matter if your phone drops from 20% to 1%… as it should never go below 20% and never above 80%. This is to keep your battery happy and running for as long as possible.
Btw. that your battery drops from 20% to 1% means, a drastic drop in voltage, would you be able to monitor your battery and post screenshots of it, please.
Just try any doesn’t matter. Take the first you find, or try GSAM (free version). (Don’t root it, if you don’t want to, just for this sake the normal version is good enough.)
The voltage of your battery, before and after it drops are interesting aswell as a chart if you can get that.
first observation yesterday.When the battery is on 21% the voltage was 3.61V and when goes to 19% and start drops to 1% the voltage from 19% to 1% was
19% was 3.43V
18% was 3.37V
17% was 3.36V
16% was 3.36V
15% was 3.35V
14% was 3.35V
13% was 3.34V
12% was 3.34V
11% was 3.34V
10% was 3.33V
These measured values had time and got up to 10% because then fell through to 5% and then to 1% and closed
that’s great, but what I wanted to see is this one :D try to find this page in GSam Battery Monitor please and post it.
It would be great if you can get your phone empty (that means down to 10% - 20%, not completely empty) and then recharge it to 90% … and let it go down to 10% again.
@soupis oh yes! there is the rapid drop just as you described. From 20% it goes straight down :(
Interesting is that the temperature of the battery goes up, are you doing something with your phone from 20% on? Like the temperature of the battery speeds up like nothing.
I thought it would jump faster but it doesn’t look so bad.
The only thing to say from the picture is that you have 28% app usage. Watch if for some days and post another chart (charging the phone and going down to 10%) and include the App usage please.
I am not sure if there is help, but let’s try and figure it out :)
