[Q] Xperia mini pro battery - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

hello,
i have sony ericson xperia mini pro sk17i. i have a very general question. i know it is stupid but i have read so many contradicting views that i thought i woulh post it here.
SK17i has Li-poly battery i guess (i am not sure) . what is the correct way to recharge the battery so that i can get maximum recharge cycles?
Upto what level should i discharge the battery so as to get maximum battery recharge cycles???what should be the charging procedure??

Nothing of this has been confirmed as 100% accurate.
First time charge 12 hours.
Everything else is questionable at best. Li-ion/poly batteries do not suffer from memory loss. It doesn't matter if you recharge them at 40% or 4%. You will brake Lithium battery only if you rupture a cell thus losing part of its capacity. And you can't prevent that or intentionally invoke it. So when someone says batteries lose some of their capacity over the years, they really mean, some of the cells die. Only thing you can do is get quality original battery and hope for the best. If you put cheap Chinese counterfeit battery, its cells will usually last much shorter then the OEM one.

G2/Hero Initial Charge - advice please

Hello everyone,
Getting my G2 tomorrow ad was wondering what's best to do for the initial charge ?
What did you all do and how do you find your battery because of it ?
Cheers James
hi there mate
I did a 3-4 hour charge until the battery was fully charged...the orange led charge thing goes green and its fine then
right now im managing to get a day with heavy use, which is good
Thanks immya
Any other advice please ?
I atcually do the same. But i repeat the process of fully charge and discharge the phone completly about 2-3 times. So the battery gets well trained. I repeat ist about every 2 months. I know it should not be relevant with those new batteries, but i found out it is, and the battery last longer.
jut my 2 cents
Cheers,
Chaos42
it's 2009, just charge it and use it.
when i got mine the battery was ~1/3 full, i charged it till ~2/3, then had to leave and completed the initial charge like two hours later, all works fine, getting somewhat between 4 hours and 3 days of usage.

Hey chaos42
What do you mean should not be relevent with the new batteries ?
Is there some sort of new batteries with the newer phones ?
Thanks
James
no, what i meant was what immya just said. that with the modern Li-Ion batteries you should not worry to much about how and when to charge. I just wanted to add that even it is 2009 i observed a far better battery lifecycle and stamina when you try to take care of your batterie. and charge it as decribed. that's my experience. at least for the initial 2-3 charges.
cheers,
chaos42
not that i am trying to discredit you here (in fact i would be very interested in such numbers myself), but did you do any tests or comparable setups to check the difference? because if we are talking about "a feeling" that you have this is IMHO not really relevant data. i would like to see two identical phones in a (at least) similar environment, performing the same tasks the same amount of time a day, and with that getting different runtimes on the battery for a period of a few weeks. these two phones don't need to be heros necessarily, as long as they have the same type of battery and can produce comparable results, but as long as this doesn't happen i myself rely on the tone on li-ion batterys in general. which is (and i am not able to quote or prove this): they are robust in terms of regular charging, and worrying about wearing the batterys in or training them isn't worth the effort. again no discredit here, but as long as no comparison has taken place there is effectively no data to analyze... just too much variables.

NiCad batteries work best when fully discharged before re-charging otherwise you get what is called the memory effect. If you are in the habit of topping up before being fully discharged the better 'remembers' how much you let it drain before charging it and then get's the idea somehow that this is what its capacity is and goes flat at the point that it 'expects' to be recharged.
NiMH batteries are much less prone to memory effect. They are the ones that need the 16 hour first charge then subsequent charges are shorter.
Li-Ion - lithium to its friends - are not supposed to suffer any memory effect at all. You are supposed to be able to top up as and when you want without any detrimental effects.
None of the above batteries will last forever and will need replacing after 2 or 3 years of daily use.

Absolutely spot on!
These days batteries do not require dishcharging fully before recharging. Even if the person in the phone shop says "ensure you charge it for 12-14 hours before you use it", this doesn't matter - once the battery is fully charged, it stops charging itself anyway - even if you leave it plugged into a charger!
Same as what's being said already.
To add, it's even better to keep your lithium battery topped. Fully discharging them is actually bad for a lithium battery. Full discharge and heat is what's bad for a lithium battery.
For a nice reference, check this: http://electronics.howstuffworks.com/lithium-ion-battery.htm
(the life and death part is what might interest you)
On a more interesting note. A long long time ago I got a MDA Compact aka Qtek s100. And there was a lot of debate here on the forums about the initial charge. In the manual it was stated that you should charge it for like 12 hours or something the first time. Then people obviously also said that was bull, because it had a lithium battery.
But! As for WM2003 it didn't save it's whole registry etc on the ROM but in the RAM. Once the battery was dead, bang! hard reset right there.
So they included a little NiMH battery in the s100 that would keep the RAM 'alive'. And that was the reason it needed such a long first charge, for the NiMH cell.
And for some reason a lot of manufacturers take an 'old' manual text for the first charge of a battery. Although that doesn't happen that often anymore. Especially in the beginning a lot of instructions of how to use a lithium battery were just plain wrong. And they put NiMH or even NiCad instruction in there!
Edit, some instructions as found here (http://www.batteryuniversity.com/parttwo-34.htm). Talks about laptops, but it's the same nonetheless.
Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

How to proper charge the battery?

I guess this could go into any category for any modern telephone, but since I am the proud owner of the I9300 I choose to post here.
The last few days I have been (foolish) enough to charge my in a way I have understood can decrease the battery's lifetime. For instance, I charged it from 9 % up to only 84 %, and the other day from 17 % to 70 %. These are merely examples, but I hope you know what I mean.
Will this damage my phone's battery and lifetime, as this being a "modern" battery?
Thanks for answering!
Charge ur dvice when its below 20% and try to charge till 100 if u can otherwise its ok no harm.
Modern lithium ion batteries dont suffer memory effect like the old nicads used to
Many people recommend not letting the battery go too low if you can help it
I have always put it on charge when i get home from work, regardless of how much charge there is, and imtake it off charge when i need the phone
The idea is to charge it as and when. Don't get all precious about "I must charge it at xx%". This is a myth. Simply charge it as and when you need it.
It doesn't matter if the battery goes low. True, depleting a li-on battery to 0% will do sever damage to the battery. You need to keep a good 15% charge in the battery BUT what your phone reports as 0% will be that 15%. The batteries are designed to keep that buffer so that it is impossible for you to break it by letting it run "dead". These are limitations built into the battery at manufacture so there is nothing to worry about.

Battery calibration.

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.

how does that answer to my question ? Do they sell new x10i ? meh

[Q] What the best for the battery?

My old phone's (Xperia S) battery drains very fast (can't last for a day) after 2 years of use. When it was new it lasted about one and a half day. I charged it every day for 2 years and the battery became weaker. I don't want this to happen with my Z2. I use dock for charging my Z2. USB cable or dock is better for the battery? And when should I charge it? wait while the battery drains full or charge it every day and don't let it drain, just about half, or don't charge it full and get it drained every day. And how long should I charge it? just that time while it charge full or leave it charging for longer (a whole night, about 10h)
someone please
I dont think it has anything to do with the way you are using to charge your phone... It's just natural for the battery to need to be replaced after a couple of years as far as i know
As far as I'm aware, after about 500 charge cycles the battery stops charging to full capacity (although it says it is). So the battery quality degrades over time regardless.
the battery of the Z2 is hardly affected by how you charge or how many times its charged
itll start degrading over time
it should be a Li-ion battery (referencing the packaging instructions for Z2)

yeah, I know that it's affected by how do I charge how many times, but I wanna know that what's the best for the battery

just charge normaly,
somehow i get the best life out of charging randomly, e.g. never 0>100% or simular but instead 20 to 60% increments gives me the best total life
in terms of wear, cant do anything with a Li-ion battery as far as i know
ok, better charge it when it gets as low as 30% and better not fully charge it, but 85-90% will be great for long term life. and never let it connected if it happened to reach 100%, also better keep it somewhere cold and definitely not under sunlight
It is said to live longer if you charge it from 50 to 90%.
That said, if you charge it from 0 to 100% every 2 days, or charge it from 50 to 90% ever day.... well... the end result is the same... it doesn't matter at all.
The battery already has safety over/undervoltage protection, therfore charching it as you like doesn't change much at all. You will see that a phone left at 100% in the charger will drop to 97-95% before it starts charging again.
i think the battery in the Z2 was said to handle about 600 cycles with less than 10% Battery degration.
if you charge it every 2 days thats about 3.5 years.
There is a lot of false information floating in this thread.(and lol Z2 deals with all, 10/10 loyalty) I was actually replying to this but I wanted a bigger audience to take better care of their battery, so check my thread out : http://forum.xda-developers.com/showpost.php?p=60299964&postcount=1

Battery capacity

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
