[Q] Battery overcharging - Xperia Z1 Q&A, Help & Troubleshooting

Hello.
With Current Widget I measured voltage during charging... In 100% it is over 4.35V what is, I think overcharged, because Li-po or Li-ion have max voltage 4.2V per cell. I have rooted phone, but stock ROM and stock kernel. Can rooted firmware change charge specs. or this is way how SONY damaging their batteries so people have to buy every year/two new phone or new battery?
Thanks for answers.

It's 0.15V of difference, it do not hurts or anything. Sony do not plan to ruin your phone. You are just paranoid on Stock Rom...LOL...

I'm working with Li-po batteries in RC planes and I can tell you, that 0.15V overcharged can significantly decrease life of your battery. But it is easy way how to increase capacity of battery, but it is very bad way.
So, those limits are controlled by Kernel, yes?? And when I flashed different FW to root my phone, it didn't changed kernel, so I probably has stock kernel?? Thats the main question for me, because with previous experiences I rather stay at stock kernel and stock ROM before flashing anything custom.

Ok, also you should know that the test where you get from that 0.15V can be non Right.

You can stay on Stock Rom and flash a Custom Kernel, for that you have to Unlock Your Bootloader, and play with the settings or anything to undervolt the charging, but I think is not that simple.

On more than one occasion I've seen you post and give horrible information, in most cases, very wrong because you don't know any better. If you don't know something, DON'T COMMENT ON IT.
0.15V is a big difference when it comes to batteries as small as ours. In a car battery, sure, 0.15V isn't that big of a deal, it's less than 0.01% of a difference, something that can naturally occur with impurities in the lead/acid components, magnetic shift or hitting a speed bump too fast. However, on a battery the size that's in our phones? That's a 3% difference. 3% variance is MASSIVE in relative sizes.
I'm not saying don't help anyone, but don't fake answers in hopes someone clicks your thanks button.
On topic:
In the past, have you flashed a 3rd party kernel at any time, for fun or testing, or for daily driver use? (Even if you're stock now)
How are you plugging the device in - USB port on a computer? USB port on the side of a surge protector? If it's a computer port, is it USB 2 or 3?
Are you using the stock charging block and stock cable that came with the phone? A 3rd party solution like Belkin, etc.?
If you have access to one, plug into a car cigarette lighter, either Sony or 3rd party, do you see a change in the overcharge values? What about a magnetic charging cable?
Have you opened up the phone and tinkered with anything?

Just going out on a limb here but have you checked the app is actually accurate!!

The only way you're going to be sure if that voltage is accurate is if you use a multi meter, apps only read what the phone reads and outputs, which isn't always accurate, try getting CPUZ HW monitor for your computer and check your 12V rail, you'll find that it's nowhere near accurate whereas other apps will give an accurate reading, with this being the case there is no way of knowing which one is accurate and which one isn't, a multi meter is the only way. But in all fairness you're probably going to be using your phone for around 2 years so with that in mind does it really matter?

Take it easy dude, on more than one occasion i've seen him give perfect advice and to keep things real i've seen mods and elite developers make bad decisions and give bad advice out because they simply thought they knew, give him a break eh! Theres ways of saying things to people if you have a problem, like not doing it publicly, if you voice your concerns properly then no harm no foul, personally if you'd have just said that to me i'd be annoyed.
Just a heads up.
And as i've already said about the voltage offsets which have been talked about, in all fairness it's a negligent difference and won't matter in the overall scheme of things.

Lg l7 battery fits our OB just fine :)

EDIT:
Do the following at you're own risk.Even though it works for me and there is no logical reason it wouldn't work for you.
My wife got a new L7 couple of Weeks back and i have been paying with it every now and again.
As the battery on the OB is experiencing bad drain lately i thought to look for replacement. Tried other battery with no luck and than last night thought what the hell i will try the L7's battery.
Hell yeah ! Fits nicely ( but the OB battery had to be filled a bit to fit in the L7 , just in the right corner about 1mm on 1mm).
Now to the nice part. As it is a new battery the self drain is gone.
And it is 1700mAh
Although i will have to return it to my wife as she is gonna be in a shock as her phone is gonna be dead before tonight The big question for me is is the L9 battery the same size and would it fit as well .
I forgot to mention with the original battery the current drain is about 1% every 2 minutes .
But this is due to me using the phone a LOT. At least one and often two charges a day for year and a half so long gone the 300 charges which are supposed to retain 90% of the original charge.
can you take a picture of your p970 backcover battery?
Here goes the pics, sorry about the delay.
P.s. Pics are from the old trusty s8500 aka wave. L7 camera is crap
So L7 battery is 3.8 volt our p970 battery is 3.7 volt.Cant it be any damage on main board?
Wouldn't think so. As both mobiles work fine with swapped batteries
And during charging voltage is way higher anyway. Remember 5 volt charger
That's a nice find! Good job! Might buy a genuine L7 battery...

Nice info, thank you!
I am glad to share
But as for the L9 looks like different shape and contacts positions
Thanks gor info:thumbup:
sorry for my bad English
So is it safe despite the voltage difference?
So far so good. One day use and it is great. 4 hours + screen time compared to 2.5 (again worth repeating my original battery is degraded)
I even find data connection working better, but that might as well be fruit of my imagination.
Best part is my wife hasn't caught up yet .

Yes. Don't use it. Just because something fits doesn't means it is supposed to work. For instance I am pretty sure if I try I can fit my phone in my mouth. Is that good? NO!
You won't notice it short term but long term it will bite you and Lg can refuse warranty if it's damaged due to incorrect use.

super correct , if this was the deal lg simply would have included it at least in the models of today , but the main board will suffer on long terms of use :good:
Actually my neighbour is using razor xxx batery in his phone and that's half volt higher than his original battery.
The problem for the main board is not the voltage itself but the incoherent amperage and power consistence, and this battery is lg made so complies to their standard.
Again remember that the phone runs ok on charger which happens to be 4.8 volts without battery inserted.

Of course it's not the voltage itself, but the increased voltage causes increase current and that increases heat output and that does damage your phone.
Try this yourself.
Create a two circuits with a two identical light bulbs. Use a battery one battery that is 1.5 Volts and use another thats 3 Volts. Which do you think will burn out quicker?
And the fact that it's 1700mAh doesn't necessarily mean it gives longer battery life it might just mean that it has a higher current output.
You can use that battery if you want. I wouldn't.

It's 0.1v of diference, I don't think that could break the phone or something.

The heat output of the CPU is directly proportional to Voltage squared and since the change in temperature is equal to the Heat Ouput minus Heat Disipation the result will be a lot hotter than you think. The hotter it runs the higher the resistance in the circuits the more power you have to us to keep it running stable. Can you see why even a small difference in voltage makes a big difference.

Been reading about the battery situation...

Okay, I have been reading about how there is supposedly NO WAY you can change out the stock battery inside the case with a larger one. I understand that is so, but WHY exactly can you not solder in a new, larger unit instead please? Is there some sort of firmware that will only support the stock battery or is it another kind of issue?
Can anyone please explain it to me? I have advanced skills for soldering, so I can handle pretty much anything barring a motherboard issue...
Its a kernel issue. The battery is controlled by a custom driver.

I see, that is disappointing. Has anyone tried to tackle this? I'm guessing a resounding "NO". heh
I'm not positive that you couldn't use a larger capacity battery but it probably would be physically larger and probably wouldn't fit.
Not Li-Ion battery but I have replaced a 3800mAh battery with a 5000mAh with no problem at all. This was a Ni-MH battery but a Li-Ion battery charging is a far simpler than a Ni-MH. I was able to install a larger capacity battery cheaper then an OEM. I've been doing this for years.
As far as I can tell, there is plenty of room for a larger battery inside the unit, the main problem seems to be getting it to work, yet I cannot find a single instance of ANYONE actually trying to put one in...
Are you quite sure it could be that easy? I really like this little tablet, but two things bother me: The battery life -SUCKS- and I don't like carrying external batteries with me.
As it is now I can get it fully booted and online in under a minute and all that is needed is to keep it running for more than a few hours and I will be very happy. (Well, until we get a finished version of ICS I won't be really really happy, but LOL)

Why bother with ICS, when CM10.1 (Android 4.2.1) is more complete, better performance and battery life?
Also, look into your wifi sleep policy settings, this has a huge impact on battery usage when in standby.

The algorithm for charging a Li-Ion cell is simple. It won't matter what the capacity of the cell is but the charging rate is something that you can't change so it'll take longer to charge.
I have a automotive scope that uses 1600 mAh 7.2V Ni-MH pack stuck inside the unit. A PITA to change, it had standard RC type connectors so I installed a extender to go outside the unit. The OEM packs use "AA" cells but I had a 7.2V pack built using 5000 mAh sub "C" cells which I Velcro to the case. I could have used "D" cells which are up to 12000 mAh now but it would have way too bulky. I normally charge the packs on an external charger for speed although I do have it charge with the unit at times.

[Q] whah about charging the one with ..

is it good idea to charge my htc one with an samsung 2A charger rather than the 1A ? iss harmful for the battery ? whats the cons and pros
Should be fine; the phone won't take more than 1A. It might only take 0.5A if the data pins aren't shorted.

try searching (sorry not kidding), but there is a thread here in Q&A with similar question, and some very experienced electrical engineer & phone repair dude gave a very long description.
if i remember correctly, the phone won't use anything more than it needs, so going over 1A is OK, the phone will only use the 1A
on the other hand using lower level charges, will over the long term damage the battery.
i'm no expert in this, go searching for it, it was a quite interesting post. (sorry, i didnt bookmark it, if i happen to bump into it, i'll let you know)
Yup you are correct. I know i have answered it a few times in other posts. heck maybe im the phone repair dude your speaking of.. Or not.. LOL
Basically the phones Kernel will not allow the unit to over charge. There is hardware (that talks to the software) that limits the maximum amount of input current. That has been set by HTC at around 1A. So if you hook up a 2A charger your fine as the device will only draw 1A max.
I my self ran across many blackberry playbook tablet chargers dirt cheap and have them at work and home. They work great for charging everything from tiny Bluetooth devices to full blown tablets.
HTC sold us devices with a non removable battery. So they decided to not allow us to charge it to fast to reduce the heat and maximize battery life.
Remember the two most damaging thing to Li-Ion is heat and extreme low voltage.

Where to get replacement batteries

Oneplus 3 is an awesome phone no doubt (if you don't damage it). However with the dash charging, there's a high chance we might need replacement batteries for the phone after a year or two.
Does anyone know where we would be able to obtain dash capable batteries for replacement? It would be a great disappointment if we are not able to replace it.
*it is a concern because at least in Singapore, there is 0 support despite purchasing a local set. You will be given an email to make an appointment to bring your set down to a location, but NO ONE will respond to your email. Oneplus Singapore Facebook as well as official reseller do not provide any support either.
Why would Dash Charge wreck the battery? Afterall if anything the phone heats up less than other phones, because the charging is handled by the adapter, not the phone.

You have a point there. However, batteries will eventually degrade, so it would be great to be able to do a replacement when the time comes

Most damage to a battery is done at night when you charge a phone when you've gone to sleep, as the charger will put it to 100% and keep it there throughout the night, which puts more strain on the battery. (just look into Sony Qnovo battery charging tech in their new phones).
The dash charger has been proven to change people's charging habits. For example I wake up at 7.30am to go to work at 9am, as soon as I wake up I put my phone on charge. Thus meaning it stays at 100% for less time, and so degrades slower.
just keep your battery b/w 40-80% and it's all good

Stay away from buying non oem batteries. You don't want your phone to be the next Note 7 lol.
Again you wont need a new battery. It degrade really slow. The problem with fastcharging is heat. Batteries dont like heat. Also charging overnight is bull**** since it stops charging when its 100%. Again it doesnt matter what you do.. If u drain it to 0% its not fully empty so really doesnt matter!

Personally I change battery ever 1.5 to 2 years. Batteries have a lifespan and degrade over time. It degrades faster with heat. It's quite disappointing that no one is sellong replacements though.

Exactly. The controller stops the current flow at full charge. It will not top it up if you keep it plugged in such as in the overnight scenario.

The model number on eBay is BLP607.
You'll need BLP613 for OP3.
Maybe after a longer time there will be more replacements, if there aren't already.
If the OnePlus's battery it good I don't see a need for a replacement personality because I change phone after 2 years, when factory support ends and I'm tired of the phone.
I am pretty sure you can't wait to buy a new one before the battery degrade to an unacceptable level.
Like my OnePlus 1, which still has a quite decent battery time, though it has already become my son's toy.
So, don't worry about this too much.
Majority of the users will replace their phones instead of a degraded battery within 2 years. Unless the battery is defective then yea that would be understandable. If you are one the minority who upgrades every 3+ years then kudos to yall for having the will power to resist the upgrade fever.
is there no one who works at one plus and also uses xda?
that dude can help us in getting batteries from the supplier of one plus.
I am using my xperia ZL since 2013. i changed its battery a while ago. now i feel it is time to change my device. moving on to one plus 3 soon.
I think my OnePlus 3 battery is pretty broaken already. Last me for around 4 houers so i need to recharge it several times a day.
I cant find a original battery, so ill probably have to get a not OEM one

AccuBattery says my battery is 87% helathy and on 2611 mAh instead of 3000mAh, but feels like much less

Is it possible to connect 2 batteries and use as one?

I've got two original Samsung note 5 batts. They currently have 2300maH and 2800mah capacity left.
I searched online for this, I only found here in xda a threat, someone said that if batts are same model and parameters connecting them might work....
Please comment
Probably not a good idea. If one shorts internally it may get fed by the other. Double trouble.
May screw up the power controller ability to effectively monitor charging and lead to a Li failure.

You can try it. I'm not real keen on the Frankenphone thing. Using frequent midrange power cycling (40-80%) may be a better plan.
what will happen if I connect battery for another model of samsung, something like 5000maH? (assuming, the batt. has same voltages..and parameters)

It will probably charge normally as I believe the charging is voltage based. Whether the battery thermal sensor will work correctly is another concern. That is important as it helps set charging rate and the under/over temperature behavior of the controller. It may take longer to fast charge as the power controller circuit may not be able to sink that much current.

ok, thanka for the information.I could go deeper to check if a script could make custom-management of th. sensor ,based on diff. parameters of battery, but I even if it can, there would be other problems i guess; lost cause

You're welcome.
People do create Frankenphones using huge batteries but they are awkward and more likely to be damaged in a drop. As glaxys graphically illustrated it's a crap shoot if it will go supernova on you. An optimized Samsung will generally get good SOT with the stock battery.
