how to change battery on samsung s7
- #i
Is it possible to reset the telephone batt_cycle entry?
Reason: after changing the battery I realized that the new one (original Samsung as far equally I can tell with man. Date 11/2017) does not perform as expected. The observation is that the battery is not charged to the correct final charging voltage of 4.35V merely instead charging is stopped at iv.2875V indicating 100%
This did confuse me - after all that'due south throwing away with some juice that could notwithstanding have gone into the battery.
Further investigation shows that the irresolute of the battery did non reset the batt_cycle to 0 but instead information technology is counting onwards! Comparing the readings to those of a S7 withal with it'south original battery but with many cycles shows that the old battery also stops charging at iv.2875V.
I'1000 suspecting that the voltage is lowered on higher battery wheel to prevent harm coming from overly demanding charging an quondam bombardment. Simply now with the battery changed to a new one a lot of potential is going down the bleed....
That's why I'one thousand request. How tin the counter be reset?
The topic is discussed in length and with further info (in German) here (especially upwardly from post 41 onwards - you will also find a tool there that reads out several corresponding values of the battery):

Hello to the pro's here.Is information technology possible to reset the telephone batt_cycle entry?
Reason: after irresolute the battery I realized that the new one (original Samsung as far as I can tell with man. Date xi/2017) does not perform equally expected. The observation is that the battery is not charged to the correct final charging voltage of four.35V but instead charging is stopped at 4.2875V indicating 100%
This did misfile me - afterward all that's throwing abroad with some juice that could still have gone into the bombardment.
Farther investigation shows that the changing of the battery did non reset the batt_cycle to 0 merely instead it is counting onwards! Comparing the readings to those of a S7 all the same with it's original battery merely with many cycles shows that the onetime bombardment likewise stops charging at 4.2875V.
I'm suspecting that the voltage is lowered on college battery cycle to prevent damage coming from overly demanding charging an old battery. But now with the battery inverse to a new one a lot of potential is going downwards the drain....
That's why I'g asking. How can the counter be reset?

At that place is this code *#9900# that brings a card and at that place is an choice called "BATTERYSTATS RESET" at the bottom, however i tried this and did non deleted discharge cycle number, and then i estimate there is other code for that.

@slackstring hat herausgefunden wie homo den Wert zurücksetzt!
Vorab: Root wird benötigt!
Root/efs/factoryapp/batt_discharge_level
Da drin befindet sich der Wert "batt_cycle" im Format xxx,xx. Ich hatte einen batt_cycle von 674 und in der Datei stand 67439. Habe diesen auf 2800 zurückgesetzt da das der fg_cycle Wert meines neuen Akkus ist. Siehe da, nun habe ich einen batt_cycle von 28 und fg_full_voltage ist wieder bei 43500
Achtung!
1. Bitte nicht den Wert zurücksetzen wenn ihr den Akku nicht getauscht habe. Wir wissen nicht wie sich ein modify Akku verhält der wieder ganz voll geladen wird
two. Wichtig!! Macht mit TWRP ein Backup der EFS Partition bevor ich anfangt etwas zu ändern.

A lower battery voltage would also extend the battery life span of a young battery, but let's be honest:
Who on earth likes to charge slower?
I cherish fast charging.

At least it got recreated by the organisation.
"1" is all system had to say near information technology. No 0's. Plus he says permissions are 600.
Battery went from 95% to 63% in about 20minutes.
ThunderTweaks was stating 56% battery wellness beforehand on new original battery.
Id say information technology worked.
But you can never be too sure.
on BlackDiamondN8 5.1 and ThunderStorm kernel ii.3
Happy new year folks!

Just use B7000, information technology's fabricated for exactly these kinds of phone repairs. Holds tight, flexible, just easy to remove with heat if needed for future repairs.
I used a combination 2mm foam record and B7000 glue and my S7 is waterproof co-ordinate to pressure level tests.

Will definitely endeavor that adjacent time. I did see the B7000 while searching for mucilage, but I merely opted for Mannol as its likely better for waterproofing, and I don't mind replacing the back drinking glass every two years or and then when I supercede batteries.
Thanks for the suggestion! :good:
