Hi, I was asking myself if it was possible to copy batterystats.bin from a calibrated x10i to have our own x10i calibrated.
I explain : I see that file like a file with values that have the percentage of the battery with the duration and stuff like that, so copying it to have the right values.
Can work or not ? influenced by kernel or rom ? What do you think ?
Li-Ion batteries just need a good charge for approx 8-12hrs when new and first installed and having this process repeated for at least 4-5 charges.
The phone doesn't allow the battery to over change and cuts out and then starts changing again once the charge drops to a chargeable threshold.
This allows the battery to achieve it's maximum charge.
Li-Ion batteries should never be drained or allowed to run flat and should be charged regularly.
If you completely discharge a lithium-ion battery, it is ruined.
Li-Ion battery life is between 2-3 years.
I would let the battery sort itself out as all the battery status is based on the battery itself.
If the battery is old and on it's last legs, it'll have less charge than a newer battery.
P.S. If you plan to keep and use the XPERIA X10i for some time, it's well worth buying a Mugen Power 1800mAh battery.

So I'm running my aria on CM7-07282011-Nightly. I'm having battery issues, not battery-life issues, but general battery function issues. My stock battery died, then I bought two identical 1500mah batteries, which I have been charging with a standard Li-ion smart charger which I normally use for battery packs I build for various other projects. I just charge one battery while I use the other battery. Anyways the problem is that my phone's battery meter will never go over 80%. I boot up on a fully charged battery, and after two or three minutes have passed(when it first boots up it just shows the % it was at when I took the other battery out), the phone reads something like 74%.
I've thought maybe there was just a problem using two different batteries, so I tried charging one of these batteries in the phone and of course they stop a little above 70%, and sometimes the battery even drains while plugged into, well, any, of my 4 AC wall-plug type chargers or my computer.
I've tried wiping the battery stats, but it didn't do anything, and all the calibration methods I see say to charge until it's at 100%, which I can't get to...
I just wish there was a way to plug in an externally charged battery and reset the battery meter and force it to recognize whatever value is actually 100%....I've searched these forums and googled for two days and found no solution.
Does anyone know how I can fix this??
Try fixing permissions

I'm not sure if there is anything you can do about it. There's almost always going to be some quirks with third party batteries.
A tip is never get 3rd party batteries and the batteries we use love charging so charge whenever possible because if you let your battery die before charging waste builds up and leaves less space for charging.
Signatures are fancy.
well, the phone works as long as if the battery has been charged to 100%, so I just wondered if the was something I could do...
So even if the batteries work a long time when fully charged from my external charger, there is no way to fix the battery meter? If I continue using it normally would battery stats eventually callibrate? they are good batteries...just seems like a software problem to me
Where did you buy the batteries from, E-bay??? E-bay and other on-line markets are loaded with Chinese knock-off batteries & SD cards that are fakes and/or not to manufacturer spec products.
If that's what you have, you can't expect the phone to "fix" it.
Battery stats do take a few days to calibrate, but I believe it should still show 100% when charged, if you have a real battery and not something out of spec.
I don't know what the manufacturer specs are, but a fully charged battery reads 4.2v, well within standard Li-ion open-circuit values. There is nothing wrong with these batteries....

Problem is that the percent battery available is not determined my measuring the cell voltage, rather reading a value out of the fuel gauge built into the battery pack. Li-Ion batteries have a rather flat discharge profile then crater at the end, making the cell voltage an unreliable predictor/measure of battery capacity.

Does leaving your Galaxy Note plugged in after it has reached 100% charged harm the battery?
From what I heard and read numerous times, you shouldn't leave a phone on a charger for more than 24 hours. I have heard many different opinions on this, but I think leaving a phone to charge overnight (6-10 hours average???) on a consistent base shouldn't harm the battery in general.

Hard to say how many charge cycles the OEM batteries are rated for.

No Memory Effect
Lithium ion batteries have no memory effect, as seen in Ni-Cd and Ni-MH batteries, from which repeated charging and discharging reduces charging capacity to an insufficient level.
Long Life Cycle
Lithium ion batteries last through more than 500 repeated charges and discharges, making them very economical.
also from other readings...
I am pretty sure that Lithium-ion batteries for smartphones cannot be overcharged because the device's circuitry stops charging the moment it reaches 100% and allows it to drop a certain % till it recharges. That's why sometimes your phone's battery % will reduce so quickly after a full charge because it is really not at 100% when you unplug it.
Manufacturers, however, will still recommend disconnecting after a full charge.
Another...
it is not good to allow your Lithiumo-ion battery to fully drain then recharge repeatedly, as many suggest, to "train" your phone...that's puts a stress on the battery and is not good.
A low % (15-20%) then recharging to full one time will reset the meter and make it more accurate but not lengthen the batteries life.
all that said...I plug mine in at night and unplug in the morning.
This link talks about the Samsung battery and charging. It sounds educated on the issue but who knows....

Summary
1. Use wall charger not computer
2. Unplug when charged
3. Don't recharge until battery is below 10%
I put the phone on my desk dock every night whether it needs it or not. I do find myself topping it off too much also.
Since the battery on my newly acquired Razr Maxx can't be removed and replaced, how long will this phone last me? Charge cycles?
Is it OK to drain the battery all the way down (charge every other day) or will that shorten battery life?

No Official number but in general batteries typically are spec'd to last 300 cycles before there charge is 50% capacity of what it was new, So I always make it a thing to go aslong as I can hold out between charges, just don't try powering it on if it shuts itself off from low battery, that is a fast way to kill a battery, also there are tutorials on how to crack open the case and replace the battery if you end up needing to, but by that point you will probably have moved on to some quad core phone that will be all the rage in 2 years.
With li-on batteries, its best for the battery if you charge around the 40-30% mark. There is a chart out there somewhere, but I don't have it handy. You also don't have to worry about a memory any more
Yes... Only Ni-Cd and Ni-MH batteries have memory problem and Li+ doesn't have those issues...
Top-up the battery whenever possible + need arises... This also reduces battery getting hot, comparing charging from say 10% to 100% at a single stretch... This is useful as Razr/MAXX has non-removable battery....
PLEASE DON'T LET YOUR BATTERY TO GET DRY OR 0% LEVEL and PLEASE DON'T CONNECT TO MAINS FOR LONGER TIME after battery becomes 100% charged... Only these two must be avoided...
...
Perform shallow discharges.
Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Don't leave it fully charged.
Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. If you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health.
Fully discharge it once a month.
This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries". This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

Is this true?
you can be as neurotic as you like over this, but it really d doesn't make a lot of difference, just enjoy your phone.

The only big no no is to constantly discharge to below 5% and recharge . That according to the experts leads to a much shorter battery life .
Yes leaving on charge is a waste .
Wiping Battery stats does not improve battery life .
But all this is an old story posted time and again and bring nothing new .

It may be a waste but is it detrimental to the battery? I always plug my phone in when I go to bed and take it off the charger when I get up in the morning.

there is a built in feature that stops charging once battery level reaches 100%. so there will be no harm to your battery. I have doing the same since gs1
My old Nokia 3510 needed a battery replacement after 4-5 years since it only held 3 days worth of charge instead of the usual 7-8.
I constantly let it discharge from 100% (overnight charging) to empty, the replacement battery cost me 5 bucks.
My Galaxy S1's battery has, after 2 years, no observable loss in capacity with overnight charging to 100% and dropping to 10-15% over 1-2 days.
A replacement battery would cost roughly 15 bucks.
I could go on the same about my Laptop, Netbook, Tablet and other devices with rechargeable Li-Ion batteries.
The point is; don't try to forcefully extend your battery life, enjoy your phone. Most people replace the phone every 1-2 years and the batteries are designed to live that long with high usage and deep-discharging. If yours should not or you plan to keep the phone longer, a replacement battery is cheap.

All Lithium batteries have it (and need it) since there is a risk of damage, fire or even explosion when it is overcharged. That's why not the phone but the battery itself has the corresponding controller. Since the controller cannot measure the exact capacity of the battery (only an estimate), it is recomended to deep-discharge and fully charge (charge-cycle) the battery once in a while to reset the controller's counter.
Battery replacement is cheap and easy as abc. That's the benefit of having removable battery. Just enjoy your phone.

Still no one answered my question... :silly:
Is the small 40%-80% charges better for the long-term battery life?
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?
