Well done mate! ..still waiting for the ZTE battery, damn the post offices takes TOO long lately :(

---------- Post added at 01:09 PM ---------- Previous post was at 01:04 PM ----------

BMS or Battery Management System is a special circuit to protect from:

Overdischarging

Overcharging

Reporting the state of the battery to the phone(health and percentage)

Rate of charging(limiting if needed) according to specific temps - Not all bms have this

-------

No need to worry about capacity, 99% of them don't care about that as they can't measure it, they care about voltages ...typically 4.2v is the max charge in this type of batteries and battery should go below 3.6-3.7

All the above is knowledge from me but feel free to confirm it(google it or anything) - I'm doing too many stuff in my life and I just know a few stuff :D
[ONE Accessories] I_did_it_just_tmrrow:
THX for your information. I test allready the lowest voltage with this accu with a orig. BLP571 controller and it is about 3.3V, if you going below this voltage, the controller seems to be tell the system that the accu is to low and you got the "low battery" (with chinese signs) message when you start the system. As I know and I am really sure the highest voltage is 4.35V. Because it is a high LILO accu.

Here is the last screenshot from today. I disscharged my ZTE-Mod-BLP571 accu manually with my Sky-RC (MC3000) exactly to 3.3V, because my phone would not go below 3.7V. Maybe I calibrate the accu this way but I am not sure. Here are some screens:

Does anybody know what is about the batterySTAT on Android7? Did I need do delete it or is this a fact from yesrterday? I read that this is obsolete and I think it is.

[ONE Accessories] Awesomeness_1307:
So you've succesfully done the mod? My battery is degrading as well, and I would like a replacement. Is this mod a stable and safe option to go for?

Also, sorry if this is a stupid question, but.. the change in battery does not contribute to the instability of custom ROMs, does it?
[ONE Accessories] blend800:
my zte blade x3 battery came today

battery date from 26-04-2017 :)
[ONE Accessories] Awesomeness_1307:
After you do the mod, please share your results.. ??
[ONE Accessories] evronetwork:
at last!!!
[ONE Accessories] evronetwork:
Not sure if your battery is original, they've stopped producting this in 2016 :P ...but who knows, you'll know when you do the mod

I'll try to do the mod ASAP
[ONE Accessories] Awesomeness_1307:
Thanks.. I've been really looking for a battery replacement and need a guarantee from a user before doing this mod.. Please share your results after doing it :):D
[ONE Accessories] evronetwork:
Right now I've removed the thin laminate film(it's like a metal shield of the battery with the ZTE sticker) and the BMS of this battery, soon(maybe not today) I'll open my phone remove the EACHTEK battery I'm currently having(useless barely lasts half day ~2.000-2.300mAh right now after a couple of months) and use that chip for the battery(don't want to ruin my original as it has some juice and it's my fail-safe situation - not an ideal but so far the best but I was lazy to replace again the battery as I was waiting for the ZTE battery)

P.S. Ideally it should be something impressive going from 2-2.3Ah to 4Ah :D (or 4.000mAh if you prefer)
[ONE Accessories] blend800:
From today with ZTE battery
[ONE Accessories] Awesomeness_1307:
Wow, so, the mod was successful!? Congratulations! Please share your AccuBattery results after a few days :)
[ONE Accessories] borzowsky:
So how many hours of SoT?
[ONE Accessories] Mr.Ak:
Can you please post more screenshots after usage? Looking forward to this mod,thanks. :)
[ONE Accessories] blend800:
I will do that :svetius:

Android batterystats show me only when I'm under 100% so I can not tell you that correctly:cyclops:

I can do that but as I said Android batterystats will only be displayed below 100% :silly:
[ONE Accessories] Mr.Ak:
So,it is still at 100%?! :eek:
[ONE Accessories] blend800:
no so it is not until the battery is below 3.100mah we see the Android batterystats correctly I am just 76% battery

Sorry for my english
[ONE Accessories] Messatsu:
Thanks for all your feedbacks guys! Finally some hope for our Oneplus One <3
[ONE Accessories] evronetwork:
People get a usb meter ...no matter how accurate the software is, it can't compare to an external device. It's less than 10 Euros and last for well lifetime, you can measure any phone, tablet, bluetooth device to learn about real capacity

Drain the phone to 0% and let it shut off, don't turn it on you connect the usb meter between the charge and the phone and let it be....you'll know the time, the capacity, the average charging rate and many many other useful info - it's so simple, stop bothering with software and SOT and other stuff. Each user have different experiences which consist of usage, brightness, settings, cpu activity, calls, wifi signal, cell signal etc etc. We need to know the real capacity not everyone's habit :P

If i get 4.000mAh and have my battery last half a day it's my fault not that the mod failed ...so simple
[ONE Accessories] I_did_it_just_tmrrow:
I own a mah-Meter but my Sky-RC charger give me better results. My accu has about 3500 mAh.

It need some time to take my accu down to 0% accu, but when, I can grab on my usb-meter out and plug in in when the BACON recharged to 100%.

Greetings by Idijt
[ONE Accessories] blend800:
have now changed back to my old battery. my phone went out today at 40% and I could not turn it back on. I think that the BMS has a damage or the battery itself. It was worth trying to get a better battery for me :good:
[ONE Accessories] Inkazzo:
The Sky RC MC3000 charger [MENTION=3729682]I_did_it_just_tmrrow[/MENTION] is taking about is a nearly professional, accurate and also really known charger device in the Battery/RC/Torchlight scene. This charger cost about $100. A USB meter is OK and will do the job but you can not be sure.

[MENTION=4707793]blend800[/MENTION] your problem might be solved if you put on the Original ONEPLUS ONO controller on the ZTE battery, but as you know it could be damaged as well. I did the ZTE mod 5 days ago also with an aftermarket/Rebuild controller and do not get your shutdown problem yet. My problem is that my phone is shutting (normally) down at 0% but the battery is still @ 3,7-3,8v that means at a rest capacity of 40-60% (Note the min voltage is 3,3 Volt and max is 4,35 Volt) When i restart the phone without charging after this strange shutdown AndroidOS is jumping up to 20 - 30% and that's crazy.

Now I did order 2 more ZTE batteries and try to put on original Oneplusone BMS controller on it. I will definitely share my results with you.
[ONE Accessories] blend800:
I used an original controller
[ONE Accessories] Inkazzo:
So you put back the Origial OPO controller on the original Accu cell and it is working again?

Are you Using a Custom Rom or stock OS?
[ONE Accessories] evronetwork:
Battery fitted ...expect results soon
[ONE Accessories] blend800:
No I have not tried it I do not want it anymore I'm happy with my old battery

I am currently using RROS
[ONE Accessories] vihang60:
How's the performance (sot). Also, what's your setup
[ONE Accessories] evronetwork:
still battery 45%(ZTE Battery, 85% charge ..I've use an external charger before putting in my phone) ...seems to be holding quite much compared to previous EACHTEK battery(BMS used from this battery) - The battery could be 4.200-4.300mAh if it was longer(it's a bit shorter than original BUT a bit thicker too - still fits(back cover closes with a bit more force)

P.S. In the pictures I disassembly the EACHTEK battery(which is a fake "original") - I use the BMS so I had to disassembly the battery - In case you don't know what BMS is(although I've mention it a few posts back), it means Battery Management System and it's the chip on top of the battery

Check the thick plastic on top of the battery(this means reduced capacity ...it should be there or at least not as this as it is)
[ONE Accessories] evronetwork:
So far ...3.067mAh of real capacity ...not bad, it's the best I've seen from ANY other battery here but still far from it's 4.000mAh capacity

P.S. Might not be an original ZTE Blade X3 battery after all(who knows) ..talking with the seller - I'll upload a video tearing down the ZTE battery

P.S.2 Wish to know if it would be above 3.000mAh after a couple of months
[ONE Accessories] borzowsky:
If OnePlus would seel the remaining stock they have on the website ar 40$, everyone would buy that. Can we make a change.org petition for OnePlus?
[ONE Accessories] OPOt585:
I wouldn't, a premium power bank costs less and I can use it for multiple devices
[ONE Accessories] borzowsky:
Yeah but a powerbank is something you have to carry and charge by itself.

If powerbank would be a solution, this thread would not exist.
[ONE Accessories] poronporonpompiero:
Hi guys, I followed this thread for quite some time and l think l'll try and do the battery mod.

I just want to be sure not to buy a fake one (i don't have money to waste :p).

What do you think about this one? The only doubt i have is that chinese logo on the top center.

If anyone has the pic of an original one to share, it would be a great help for the OPO community. :)

[ONE Accessories] OPOt585:
Capacity is at least 70% of the original 3100 mAh.

This is a used, OEM battery.

AccuBattery states my 3 and a half years old battery is still at 81% capacity, 18$ doesn't seem like a deal to me.
[ONE Accessories] phillibl:
It definitely has a smaller use case, but I know a lot of users have complained about the non oem batteries.
[ONE Accessories] borzowsky:
"Capacity is at least 70% of the original 3100 mAh."

not a good deal
[ONE Accessories] RedFoXite:
I have used ZTE battery for 17 days and yesterday I returned to the original OPO battery.

At the beginning, everything was fine (except for incorrect indication of the level of charge), even the temperature of the battery was displayed correctly. Later it was only worse... The battery charged suspiciously quickly and discharged too quickly (for such a capacity). The phone sometimes turned off at more than 15% of the battery (I thought it was calibration issue). Yesterday I removed ZTE battery because my phone died and it had a bootloop when I connected it to the charger. I wasn't at home so I left turned off phone for a few hours and then when I connected it to the charger again, I was able to turn phone on (after few minutes but this time without bootloops). Just after the charger was connected I saw over 50% of battery which is impossible!

It worked until my friend disconnected the charger from electricity... Bootloops have returned and nothing has helped this time, changing battery was the only solution.

I have this battery from Aliexpress: Tracking-Number-100-High-qualitty-E169-515978-515978-4000mAh-Battery-For-ZTE-Blade-X3-Q519T/32794546179.html

the USB meter showed me about 3160mAh

Edit: One additional thing - I just realized that two bluish spots (especially visible on white background) on my OPO display are gone after I switched to original battery. I thought that I pressed display too much during exchange but battery was the reason of this. That's strange
[ONE Accessories] evronetwork:
I've mention in a few posts back that I've convert ZTE battery to fit my phone, well that first charge got me 3.067mAh(if you checked the picture I've posted) ...after 1.5 month later I said hmmm lets test this again, currently it's on 3.400mAh and keeps CHARGING!! (it's nearly finished) so I expect no more than 3.600mAh but it's WAY WAY WAYYYYYYYY better than any cheap Chinese battery or even original!!

Surely the rated capacity of a ZTE Blade is 4.000mAh, far from it but better than original ....go with ZTE people and close this thread, find a good ZTE Blade original battery and just change carefully the BMS(Battery Management System ...aka the board chip) and be happy.

P.S. Some might say how come first charge was 3.067mAh and 1.5 months later it's 3.400++ ..well lithium battery need a few charge cycles to get their full capacity unless you have a cheap-Chinese which after 1.5 months would have less capacity as it was with my EACHTEK battery("original" Chinese underneath the sticker) which was around 2.900mAh and after 1 month it a bit less than 2.300mAh

--------I'll check it now on Feb give or take to see how it ages/hold capacity although it's great---------- (I'm charging it 20-80 to keep it as "fresh" as I can so it would last the maximum and do the 0-100 only to test it(using reliable external usb meter not some app - AccuBatteryr says rated capacity 2.100mAh and 67% health ..yeah right, this can't be more wrong but on the other hand I do charge it sometimes from 30 to 50 and unplug it(it doesn't hurt the battery) so the app doesn't have full charges 1-100 so it's not very accurate. I find reliable only external usb meters and the phone turned off during the process of measuring it ----nuff said, take care yourselfs people 3.449mAh currently at 0.39A(maybe it will hit 3500!! :P) cy around

EDIT: I'll post a picture when it's fully charged, from the usb meter :D
[ONE Accessories] Mr.Ak:
Battery backup and sot is even better than original?! If so,can't wait for screenshots.
[ONE Accessories] KrIstIaN430:
Do you have a link for the original blade x3 battery?
[ONE Accessories] evronetwork:
I'm afraid I might disappoint you in that, I might drain my battery from time to time to check it's capacity but after that, I'm sticking to strict 20-80% to extend the life of this battery as I want this battery to last the same time or more than 2 years :P (I can post a screenshot if you want when it's 20% but I'm not sure it's gonna help you)

P.S. sot, battery life etc compared to original mean that you should use the same rom and same kernel to have a comparison, also you should be doing the same stuff if you want to be fair. All I can tell is that the original battery have a capacity of 2.700-2.800mAh(2 years old) right now and if less than 10% if might shut down(the 10% isn't a sure thing) and this battery with the same usb meter is having 3.5Ah capacity, how you use this power is another story to be told :D

It's this one: item/3-8V-4000mAh-E169-515978-515978-For-ZTE-Q519T-Blade-X3-D2-A452-Battery/32809338835

Add aliexpress in front and html at the back (when I order mine it was 14-15 Euros now I see 11.31 which is nice) - Still don't expect 4Ah as I did(well a bit disappointed but happy it's way better than the "fake" out there which tend to premature after a month or two)

P.S. Here's the picture I've promised of the usb meter(and yes it took 3 hours and 18 minutes to charge it ...wow that took a while)
[ONE Accessories] borzowsky:
My question is, is the % on the phone expressing the real power of the battery or not?
[ONE Accessories] evronetwork:
You wanted SOT ...oh well, here you go

P.S. still as said that depends on the rom, usage, settings, brighness and pretty much many factors ...all you need to know it's I have 3.5Ah battery capacity which is far more than the original 3.1Ah battery
[ONE Accessories] Mr.Ak:
Wow,this looks great,and that too on oreo!

Can you post the link from where you bought? Does the seller ship to India?

P.S: I'm waiting for another thing which I asked you to send to me. :v
[ONE Accessories] yogirug:
Hi,

I'm also looking forward to buying this one. I'm from India too. Where in India?
[ONE Accessories] evronetwork:
(glad you like it but as said the available capacity for my situation is 3.5Ah what I'm doing it with that capacity is up to me :D )

Both check the link I've given a couple of posts before ...it's an aliexpress seller(don't trust aliexpress anymore but didn't find an alternative that didn't cost TOO much, found some but the battery was too old for my taste)
[ONE Accessories] Mr.Ak:
Thanks! Worth to do this mod even if the original battery is at good capacity (~80%)?
[ONE Accessories] MrTapa:
Hey guys. I read some recent posts and what I can gather is that there is no easy way to get a brand new battery that just works for the OPO, now my OPO is 4 years old(well since release). And it has been in use ever since, not by me for the past 2 years tho, I have a oneplus 3, and I bought a 5T to the person who was using the OPO, now its kinda like a really good backup phone that I would like to fix, and can I ask is there like a decent battery close to the original that I can just order, swap out and be good to go. I see that you guys have managed to get 4000mha batteries and so on and benefit using custom controllers and so on but for the the work into that isnt worth it as the phone will not be a daily driver anymore. TL;DR : is there a nofrills option for battery replacement that is better than a 4 years of usage original battery
[ONE Accessories] vicky2131:
Note for people from India:

Just changed my battery today from Oneplus service center. It's original battery from Oneplus with manufacturing date of August 2017.

Had very bad battery drains and SOT was around 2hours max so had to change it.

Edit: Just showing you guys how the package looked(the battery inside is my old replaced battery)

Wow. Which service center in India? I am from Chennai. My SOT is reduced to 2 and half hours and I also need to change my battery. My phone is rooted and currently running Lineage OS 14.1 with all sort of mods. Will it be a problem in service center?
[ONE Accessories] vicky2131:
Coimbatore's service center. I had been following with them past 4months and got a call on Dec 30th that they have new stock of Oneplus One batteries(around 20 batteries). I'm running sultan's 14.1 and i don't think that's an issue!

Here'a a google map link of the shop with the phone number and everything you might need.

[ONE Accessories] aravindhramachandran:
Thank you. It will be difficult for me to travel till Coimbatore. I will enquire in Chennai service center as well. If they too got new stock means it will be great. How much did they charge to replace the battery?
[ONE Accessories] vicky2131:
Yes, better to try in chennai. It costed Rs.1900 for the replacement including all the charges and taxes.
[ONE Accessories] dwnecrid:
Im thinking of trying to do the ZTE mod because my battery is starting to die farrrr to fast for my liking. By the end of my work day itll be mid 30s low 20s for just light use and sitting in my bag 90% of the time.

Since i dont want to mess my original battery up just in case, should i order a replacement one for the bms? [Found one for 15cad] Then just order the ZTE blade battery so i can not risk having a dead phone? Also would there be any other places online youd all recommend purchasing from besides ali? To get a battery in from then would take a month or longer since im in Canada :/

ps: i do have history with electronics among other things so i think doing this would be within my skill range, just unsure about parts

Thank you for any future help, im new :(
[ONE Accessories] evronetwork:
If you have 80% capacity and zero issues don't do it ...the fact I got a battery of holding 3.5Ah doesn't mean you'll get the same. You might have lower capacity or more it's still a risk

That's my advice :D
[ONE Accessories] nartex2:
Emailed Oneplus support. They indicated battery would cost $18 but phone had to be sent in. So possibly shipping and minor labor charges. Keeping this thing running is almost a matter of pride now. I'm not at the point where I need to do it yet but getting there. It's cool to still be using phone from four years ago.
[ONE Accessories] Inkazzo:
I did order 5 ZTE-Blade batteries and tested them using my semi pro Charger MC3000 with 5 cycles (charge/discharges), they all got a printed with production date 30.10.2017 and a total capacity of 4800 mAh :eek: this cant be true

Here are the results of all 5 accus with 5 test cycles: (sorry not able to upload my pictures yet cause of forums restrictions) Now in my next Post

1. 3897 mAh

2. 3942 mAh

3. 3830 mAh

4. 3802 mAh

5. 3833 mAh

I also will tell the Seller when i did test the batteries in my phone.

These are the charge/discharge setting wich was used:

Charging 1 Ah with Termination of 0,05 Ah to 4,35 volt

Discharge 0,7 Ah with Discharge reduce 0,05Ah to 3,30 volt

the industrie standerd for nominal capacty tests on 4,35+ (hi-volt) lithium accus are:

Charge 0,5C ( "C" means 0,5 of mominal Capacatiy in this case 3800/2 = 1900 mAh)

The termination charge should be set in hight of 10% of the selected charge value (1900mAh) in this case 190 mAh

Discharge 0,2C (760mah)

with discharge temination/reduce 10% of the dischage value in this case 76 mAh

as you can see i did choose lower setting then the Industie standarts because i think theay are more realistic in case of phones.

The total test time for all 5 Cycles took 2 days 18,5 hours ;)

Today i will solder the BMS controller from my Original OPO accu and put them on to my new zte accu (ZTE MOD)

I will get back with my build-in results asap.

My tipp: please make shure the controller you put on your new batterie is build for 4,35 volt (hi volt) lithium accus, cause i putted on my firts ZTE accu Mod with 3500mAh one month ago a wrong controller wich is build for 4,2 lithium batteries and did get crazy accu percentiges wich where jumping from 0 to 49 percent when i did restart my phone.

WARNING NEVER PUT 4,35 BMS CONTROLLER ON A 4,2 ACCU CAUSE IT WILL EXPLODE!!!!!

[ONE Accessories] thegiolly:

Now 2 days ago i did the ZTE-MOD so now i got two ZTE battery (with orig OPO BMS Controller on it) with real over 3800mAh in my phone. Phone is working normally no wifi, nfc, signal or bluetooth problems because of the bigger battery.

My USB meter is showing more 3859 mAh are charged and Accu battery shows 3812 mAh , my phone was swicht on while charging but i switched on airplane-mode and set it to batterysaving mode

I really would like to upload pictures but i need 6 more posts :-/

[ONE Accessories] Inkazzo:
it is not so hard to do the ZTE OPO batterie MOD. Look at the youtube link below.

Short tutorial

1. You have to take away the Isolation from the upper side of both batteries.

2. Marke the + and - pole sides! (on the orig controller the minus conector is marked with a "B-")

2. Cut of both controller (do not short circuit with the scissor)

3. Solder on a short thin cable on both sides (do not short circuit)

4. Solder on the new controller. (do not short circuit :)

5. Isolate the controller and put it back in your phone (Your phone will not start at first you have to plug in the Charger cable and now it will)

Here are some usefull Links for the MOD
