OnePlus 7Pro modify battery design capacity - OnePlus 7 Pro Questions & Answers

I replaced my battery due to aging,the capacity of the new battery is 4400mAh。Since it is not an official battery, system shows that the battery design capacity is still 4000mAh. I try to modify /sys/class/power_supply/bms/uevent this file, change "power_supply_charge_full" from 3835 to 4400。I saved this file and quit, but "power_supply_charge_full" didn't change when I open it again.The system is H2OS, and I flashed r58 arter97 kernel. How can I modify the battery design capacity?

Interested to see how this works out. Keep us informed

4400 mAh? Where did you get this?

I bet the battery you bought isn't even 3500mah . Aftermarket batteries advertising with more mah than the original one are in 99% of the cases bs. I hope I'm wrong for you but keep in mind this could be the case. Where did you bought it? You have a link maybe?

I live in China, there are many shops on Taobao.com that sell third-party batteries for various mobile phones, like apple,xiaomi. Regarding the battery, I used the AccuBattery test, and it took about 4450mah to charge from 1% to 100%. Many people who bought the battery have also verified that its capacity is not fake. I heard that the system information about the battery can be modified only if the kernel has open permissions. Unfortunately, many kernels do not support it, including arter97.

Modified it from twrp?

I believe you, but with the experience I have this is rare. I also asked where the battery is from, if possible with a link. My battery (accubattery) is saying 86% , so I'm interested in possible replacements. Also, I worked 5 years at a repair shop for a big provider in the Netherlands so I'm no noob in hardware repair. A bigger battery normally (kinda logical) is bigger, so if the promise is 10% bigger mah it normally should be bigger and don't fit the housing. What I wonder is if the OP8pro battery could fit in the OP7pro, the connection is on the same place but not sure if it's the same. I can't find any size specs about the OP8P battery unfortunately.

I did this with Samsung note 5, bought multiply 3rd party batteries and they were all below orginal battery capicity even though they sold as higher. Also verified from accubattery, as far as I know you can't change the 4000 as it is the default but there should be a setting to change it

Thats interesting, i wanna try that too myself but im wondering... you obviously losee the warp charge function with these batteries right? How long it wakes to actually charge from 1 to 100? @Desertz

Sounds like a bad idea and you got ripped off for a fake battery

Instead of wrap charge, Qualcomm 2.0 worked on all batteries tested

Since you need an account for taobao, this is what U.S offers. Phone is made in China, batteries, so replacement battery should be from China. https://www.ebay.com/itm/LOSONCOER-...174264914155?_trksid=p2385738.m4383.l4275.c10

Alright thanks, keep us informed please I'm really curious about this topic as I kinda wanna get my hands on a new battery, mine is 82% health don't know how much of a difference I would notice if I manage to get an original 4000mah battery.
Also kinda of random question but do you know where to buy an original warp charger? Thanks

Original wrap charge from OnePlus store

Meeh there is not such a thing as Oneplus store in a country like Mexico, if not i would have already buy one.
The market is flooded with fake chargers that somehow trick the phone and it shows warp charge but if you mesure the watt these chargers will never go above 17w so is even worse than a dash charger.

Have you tried eBay?

Replacement battery issues (phone loop rebooting)

As the title says, and much to my surprise a cheap replacement battery i bought on ebay (http://goo.gl/y4RML) for my Omnia 7 makes my phone reboot constantly when put to charger or USB. Works fine when not charging.
Just out of curiosity, what is the reason for this, other than battery being a cheap replacement?
On a side note, the original battery weights 4.7g more than the replacement, as measured by my perfectly working digital scale i bought on ebay.
BUMP
I just bought another one, same problem. So I'm calling it quits and buying an OEM battery.
Same problem, I try a non original battery and now when I try to charge my original battery my omnia reboot
Decided to sell my Omnia......although I liked Windows a lot, the battery does not charge very quickly, it will not charge above about 90% and I have tried 3 different batteries, 2 or 3 chargers etc. all with the same result. The phone needs either a software update or hardware mods.......Samsung get your finger out and fix this problem......
I also found it very difficult to get a genuine battery, had to buy a 3rd party battery which did not seem as good........
Bump... I also bought 2 cheap batteries for Omnia 7, and had the same problem, although it works ok, when you plug in the charger (or microUSB on PC), after 3-4 seconds the phone reboots. and then boots again, and instantly reboots...leading to an endless booting-rebooting loop. When you disconnect the cable, it's boots ok.
The batteries I got were marked 'Made in China' (made in Korea for the original). Also they had a (slightly) different P/N: EB504465VB (chinese) vs EB504465VU (original)
I have tried to charge the battery when the phone is in Download mode. It works, but I'm afraid that the constant image of the bootloader may burn in the Omnia7 AmoLED screen.
Has anyone found any decent source of replacement batteries for Omnia7 (apart from Mugen, that is very pricey)?
same battery problem, so i bought a charger dock

Does that dock charges only the battery? Can nyou provide a link, if you have bought it online? I have found some docks on ebay, but not for omnia7 specifically. They say the y are universal for almost all types of batteries. Do you have a universal one or a omnia7?
I bought this: cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=190666195369#ht_4052wt_1134
p.s.: i can't post full link beacuse I'm under 8 post...
Grazie newfl, i found it.
The batteries that came with the dock charger had the same problem, right? What is their Part Number, EB504465VB 'or' EB504465VU?
Part Number is EB504465VB. Yes they have same issue
Have any of you noticed if the battery really is 1500mAh? The packaging says 850, which is ridiculous. Can you get through a day with 1hour calls, some IM, 2 hour music, 1 hour gaming, 1 hour reading an ebook, etc, the usuall?
I'll probably buy an original battery though, as i plan to keep this phone for at least a year more.
The ones I got are very identical to the original, and they say 5.55Whr / 1500 mAh. Their difference is the manufacurer country (original Korea, replacement China) and the last letter of their P/N (thing that might explain their incompatibility).
I didn't have the change to fully test the batteries, because of the aforementioned charging compatibility problem, but I expect my dock charger in any moment, and I will provide comparative results firstly on WPBench, then on real life.
So here it goes:
WP Bench Battery Test
==================
Settings: Airplane Mode: ON, GPS: ON (forgot it on so left it on for all tries), Brightness: LOW, Backgroung Agents: Disabled (through forcing Battery Saving Mode)
Replacement Battery: 1st:02h 40min 06sec, 2nd:02h 45min 08sec, 3rd: 02h 43min 43sec
Original Battery: 03h 41min 29sec
There is a big difference (original > replacement 34%) that I don't know if it is because of the low actual capacity of the replacement battery (despite its capacity is cited at 1500 mAh, the same as the original battery), or because of the not good charging of the dock charger (although the phone index in every case stated 100% when the freshly charged battery was inserted)

It's fake. There is no chance a company being able to squeeze that much power into a battery package the same size. Otherwise Samsung would have included a 2000mah+ battery already!

The gold brand battery capacity shouldn't be trusted. Like the post above me, there is no way you can cram a lot more mah with the same battery technology while having the same physical size as the original battery. At best you can have 10% more than the original, but from my experience, most of the original battery already maxed out their capacity for their size.

Battery Charger for my i9000m

I bought a momax 2700mah battery and Now i'm not 100% sure that the battery will charge via my phone, even if it does. it'd be nice to charge my stock battery for backup.
I'm looking into : Wall Charger
and this thing: Usb Charger thing.
I'm not really sure what to get tbh.
if it's the same voltage as your stock battery, I don't see a reason not being able to charge using the phone.
Anyway, it seems that both will work.
Also please make sure that you keep the replacement battery charged, meaning that if you're not using it make sure to recharge it once a month.
These batteries can break down if their inner voltage drops below a certain threshold.
the sgs has been known to detect some batteries as non genuine and won't charge them.
I buy a 2430MAh batery and it works fine with me. It have the same voltage of the original 3.7!

I've read that it is detrimental to the battery's life to store it while fully charged, just as it would be to store it while dead.
Since we're giving differing advice, I would suggest the OP look it up himself.

It seems to be hit or miss to whether or not the sgs knows it's not a genuine battery.. maybe it's a slight difference of voltage that triggers it, and it seems that it's the cheaper batteries that trigger it and the "oem" ones.

I've heard both, but going by my retail experience with these types of batteries. Most come precharged anywhere between 30-70%, so I can only guess that that is around the preferred charge percentage for maximum life of the battery as batteries don't move all too fast from the shelves. Heck my sgs had 70% off the start.

If it's 2450mAh and the same size as the original battery, it's fake.
I've seen these gold batteries before. Often they are OEM batteries with a fancy sticker on. Don't be fooled. Run it via a battery test, or even use Spare Parts to check the capacity. Also, avoid the placebo effect, your phone might seem to last longer and because of that you think it's a good battery but it might be simply because the battery is newer; you should consider does it run better than when you first had the phone?
If "Item location: Hong Kong, China" doesn't say enough, the free shipping and outrageous capacity claim should tip you off that it's a burn. It's just a low quality knockoff battery with a flashy label.
It's a fake.
If you want more capacity you need to buy a bigger battery and the cover to contain it, there are no other options.

That's not strictly true. You can get non-fake batteries up to 1800 mAh while still being able to use the original battery cover.

I've got the same battery. It's a big improvement over the stock battery.
I'm going to get one of these batterys and try them
And if size doesn't matter you may search for a battery with a capacity between 3.000 and 3.500 mAh, changing the battery cover. But i won't buy the one from the first post...
For me that's way to thick. :silly: I also think it's ok if the battery lasts at least 20 hours - or i'll just take another charged battery with me.
Another charged battery is a good resolution too and i got a second one cuz its my second sgs+ my old had a bath but i had insurance so i got a new device

Not a precise measurement. Orginal runs about a day. This one half a day with not much activity. It has a jump from 30% to zero. I had several full charges/ discharges before. And several attempts in trying.
lithium batteries should be kept between 30 and 90 %. It's worse to discharge them.
You could charge to only 80% but 90% is where on most phones the battery statistics reset

Sure, these are recommended usage conditions. But jump from 30% to 0% likely means defective battery, which cannot hold its capacity.
Normal battery should go smooth from 100% to 0%. Well, it may be not a straight line, but under constant average load graph should be near linear.
If it's jumping and suddendly goes 0% it's something wrong with battery. You may still try to calibrate it by full discharge/full charge several times,
but high quality batteries usually don't require it. Also I think high capacity battery must be thicker than original. If not, it's most likely a fake.

Yea, I know. I agree
anyone found a decent battery yet? For Hiking I tend not to carry a heavy powerbank (even not a light one) but a spare lightweight battery... I do not understand why Lenovo is providing a changeable battery but not selling any...
Sorry, been away without notifications. Ran battery for several weeks and notice no significant increase in battery life - had screenshots of usage but unfortunately had a bad flash (Dont use SD as internal storage).
Decided to stick with the OEM battery, and will continue purchasing them if they go out or need to swap. Because of build quality, coping with a dead phone is better than one on fire or overheating.
But if Motorola or Anker releases an extended slim battery...

I replaced the battery 3 times, still I only can use 2500-2600 mAh Capacity - help

Hello,
I replaced my old battery because it lost its 30% capacity. Then I bought 2 times original Samsung Battery and 1 time a super expensive battery from Germany.
Everytime when I test it, I use only 2500-2600 mAh capacity of my Galaxy S7.
I did calibrate my battery, cleaned the gauge multiple times, reset it. It didn't help.
I just notice that my phone charge only until 4.825 V. Do you have any idee?
Maybe a problem with the apps not the battery itself?
Those apps are not 100% accurate anyway, they cannot be as you never run your battery to 0% while the app is running
I used 3 methodes to measure it. I dont think so. How is your phones fg_full_voltage value?

What is more likely? That the apps methods are not accurate, or 3 new batteries all have 2500-2600 mAh capacity?
The apps method are known to be inaccurate so you can already forget about those results
Where is the location of that file?
There is a code you can enter to reset battery stats too
dial: *#0228#
Press Quick Start
Connect Charger so phone is charging
Turn Off the phone and leave off until battery is charged to 100%
Power on phone
Battery stats should be recalibrated
I did that already, hmm the location is /sys/class/power_supply/battery/fg_full_voltage and in the same folder 2*fg_fullcapnom shows the capacity of your battery.
You can be right with the inaccurate apps, but the apps showed me the real value with a lenovo zuk z2 and galaxz s8.That's why I'm worried

eBay only sell fakes fakes and more fakes, Amazon probably too, unless you bought an original Samsung battery from Samsung there is a high chance that all those batteries are not as high capacity as advertised
My battery life is terrible with my S7 flat, so I took my phone to the Samsung Official workshop, I thought that a brand new battery will fix the problem, the technician made some tests and he tell me that although my battery was fine with 80% wearing but my battery drain issue is caused by a faulty board.

My Third is not a fake one, it has 24m Warranty and is Made in German. The problem is with phone and OS. Nougat won't let you use your all battery capacity. If you dont believe me, use accubattery you will get max. 90%.
