Hi,
Last night I purchased my S2 and am in the process of priming my battery. Could anyone tell me what is the standard (in the box) battery capacity that is achieved after the going through a few cycles of charge/discharge I should expect?
Coming from a HTC Desire HD, I am so far impressed with the S2, way better in every respect.
Thanks for your input
Didn't know the battery capacity could be variable in a battery... are you talking about battery duration?
Talking about the value reported in apps, the like of Quick System Info PRO, where one can see the state of the battery. For example, when my DHD arrived, batter was only at 3500mV. After a week of "training", a.k.a. priming of the battery, I reached full capacity of 4204mV when charged at 100%.
I am simply trying to establish where my battery is at today + how many cycles of charge and discharge it needs to span full capacity. Talking about this for example
Breaking In New Batteries - New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated capacity.

Has anyone use the battery test in the system test? *#*#7378423#*#*? My battery not very good so I want to test it out but has been running for the last 4-5 hrs still not finish yet.
I think this will run until the battery is completely empty, so you have a few hours to go

I read on Gsmarena that the battery of sony xperia s is 1750mah but i really get shocked when i checked the battery it shows just 1500mah. What is this? Is there any problem with my phone or the info on Gsmarena is fake
use at least 5-6 hours in one day
I think it's the software. Battery test showing 1500mA but battery health test showing 1700mA.
By the way no improve and took 8 hrs to complete and only drain battery to 70% and indicated reduce capacity????
How can I maximise the battery performance?
There are a few things you can do to improve the battery performance.
Charge your phone often. This will not affect the lifetime of the battery.
"
this is what they say on their official web site,does this mean that when we charge it more often battery will perform better or what? I mean abouth batter lifetime will it make longer or just same?

As it says, it won't affect the lifetime in any way. So not better but not worse.
Charge often. Even better wait till low batt and charge. The calibration software will average it out and it will start improving. If it is not calibrated properly the phone will show low bat quickly. I had a phone showing 1% charge for over 2 hours and not die.
I've noticed many roms provide options to charge at a faster rate, many have by default now.
Just looking at CheckRom, I see that it states "(for AC: up to 1200mA, for USB: up to 900mA)". Is there any real downside to using these? Such as shortening battery life.
I have been wondering about this for awhile. Thanks.
I'm sure I read somewhere that it will only use the milliamp that is supported by the battery. Also if it charges faster it shouldn't be a problem since its using the correct power input

Faster charging equivalents more strain on the battery and thus a shorter life in terms of charge/discharge cycles.
Since the battery is replaceble, it may well be worth the few dollars to you to have it charge faster, but that's personal preference.
Quick-charging batteries leads to additional heat, I would thus not recommend it if you plan to leave it charging in a car in the summer
since that will cause even further strain. (It's very unlikely the battery could go in self-heat mode due to charging)
Actually NO, but charging with more than 1A which is stock/default will add more heat to your phone. Heat which is HOT not WARM will reduce battery life of rechargeable batteries.
Oh right, very neat. I plan to get one of those high capacity batteries (tad over twice of original) for $15.
Does anyone know if it can also reduce battery life leaving it on charge all night? I think it discontinues charging.

As every one said charging at higher rate will reduce battery life and also reduce back up time.
Secondly, leaving charger ON all night will not effect battery, because charging is cut off by internal circuit once battery is fully charged.
Has anyone checked the ROG phone "Battery health" on AccuBattery Pro? Mine is showing Estimated Capacity as 3,548 mAh, Design Capacity 4,000 mAh. I completely discharged then charged to 100% as calibration. Brand new phone.
Mine is showing 3,531mAh after around a week of usage.
Someone should report this on the Asus forums
mine also show 3500mah after 2.5 weeks of use
I have posted this issue on ASUS's Forum
https://www.asus.com/zentalk/thread-249329-1-1.html
Please feel free to add your battery capacity screenshots on their forum so we have a reference for the future
Mine's at 3462 after a little over a month. With a health of 87%
OK, then. We shouldn't be concerned. The proper way to measure battery is more complicated than what AccuBattery does (the proper way involves measuring battery discharge at a controlled rate). Since many of us are getting similar readings on AccuBattery, it's probably that AccuBattery's method isn't accurate.

Same here: 3536 mAh 88% health with Accubattery first charge out of the box after discharging to 15% following first power up.
Either Accubattery has a problem with our phone, or Asus is ripping us off.
If the batteries were bad, we'd all have different readings.
I am guessing the AI charging might affect the measurement from AccuBattery. However I also don't think the battery capacity is full 4000 mAh. My last phone from Motorola has a 3000 mAh battery on the spec chart, but the battery itself prints 2810 / 3000 mAh (min/typ). From the ROG phone tear down videos, this battery isn't marked though.
From the asus zen forum the only solution the person provided was to bring the device to a service center to get it tested
I maybe wrong however with batteries these days it only ever uses a percentage so that there is redundancy for failure and to preserve the battery life.

Samsung does that. Note 9 is 4000mah but Accubattery says 3800mah on new phones. Every one of them.
Power reserve to not kill the battery early.
Anyway, 3500 mAh seems like one heck of a left over reserve.
Our batteries should last 5 years at least
Same "problem" here, but maybe it is because program has small amount of gathered data about battery usage. I did full discharge and full recharge yesterday, and goz about 3567mAh, but ill try to calibrate battery and use measuring app for longer time to get more accurate results.
Ps: I am using only slow charger to avoid overheating to eliminate battery damaging when recharging
I have not checked my ROG Phone in any 3rd party apps as I have not had a reason to question the 4,000 MAH
It is not a problem, lithium ion battery deteriorate faster if kept fully charge all the time or when discharged to low. Since most people have the bad habit to plug their phone all the time and keep them full for a prolonged period of time, oem have to be creative to fight this. Some will show your battery is charged at 100% while in reality its only charged at 90% .That is what your program most likely reading.
lithium ion should only be charged at 100% before you leave the house, i tend to keep mine between 50 and 90 usually . With quick charge there is no reason to keep a phone plug overnight, 10-20 min before leaving the house is plenty.
I have turned on AI for battery charging and as soon as my Battery reaches 100 it stops charging which is good enough for me to have faith in the charging technology in the phone and battery capacity.
I do leave mine plugged in over night however with the right equipment to check its hard to get a good understanding of whats happening. Theres inbuilt battery health tools so i would always advise using these and going through the features of this over 3rd party jank applications and trust them. Its the only tools Asus are going to support in any diagnostic troubleshooting.
Hi guys, I am returning after some time of usage and charging. After some charging cycles I have to admit my battery capacity is "increasing" - well better say, it is getting used to be charged properly. Now I passed 7 full charging cycles, but after 3rd one every next charge had more mA. I started at 3479mAh with full battery, now I ended with 3711mAh - hope it gets even better (I'll be glad for at least 3800, but who knows?). Everytime I tried to charge only when I was below 3%.
I have to say I am using slow charger with 5V and 400mA current. Battery checker from mobile manager was not detecting any issue with this way of charging nor AccuBattery Pro. I also know, that batteries shall be charged only about 80% of its capacity, but I am still sceptical about that rest 20% so I am charging to max everytime.
Hope I helped...
...another time passed and I am back with another results. After a lot chrging cycles I am stuck at between 3500-3700mAh of total capacity. I was searching around whole internet and found out, that phone manufacturers are "decreasing" battery capacity with SW at 90% of total capacity to prolong battery life and avoid battery wear, because everytime you charge the phone, you think you are charging to 100%, but in real you are charging to 90% only - rest of 10% is "hidden" to save your battery life - due to my calculations and testing it might be true. Anybody else had something different, so we can compare it?
I've just started cycling with accubattery will post when I get some solid data but seems battery has lost some capacity already only had it since November 5

Heres mine so far only a few cycle's in but I've lost quite a bit capacity
