I'm using crDroid rom . For about a week im using the adapter of pocophone F1 in my RN7 for fast charging! But i noticed its causing me fast battery drain at stand by mode.
for example after full charge i got 1 hour sot and 8 hours of idle .
is it the adapter? should i use that or not?
NB: i didnt installed any new app or anything since i moved to poco f1s adapter from the orginal one!
I'm using my ZeroLemon powerbank with QC 3.0 support & Anker charger (QC 3.0 too) and have no such problem. I recommend you to charge your phone using original charger, because this atypical behavior could have side effects. Also, check out battery drain information — this may be caused not by charger change but by latest buggy Google Services update, if this app is at the very top of your battery drain graphic.

Hi, I noticed that my Nexus 4 charger pretty slow so I decided to check this out.
i've been doing a lot of reading here but couldn't figure out the problam.
I'm using the original charger (lg's 5v 1.2a) but charge speed is around 300-400ma (checked with battery monitor widget), with short peaks around the 600-700ma.
I tried the galaxy nexus charger (5v 1a) with both the samsung cable and the lg.. got around 850ma which is slighty lower than expected.
decided to give it a try with a friend's nexus 5 charger (1.2a) but also got only ~850ma at the most.
So I think my charger doesn't work like it should, but can't seem to figure out why other chargers won't charge full speed.
(I'm running rooted kitkat 4.4 if that's relevant to the matter).
Does anyone has any idea what could be the problem?
Thank you!!
I've never seen a full 1200mAh charge no matter what cable/charger combo I use. Closest I can recall seeing is high 900's using battery monitor widget pro.
It's possible that the charge rating I am seeing is taking into account the drain as well from using the phone. So it could be around +1200mAh but with screen on and the apps that I have running + other services (wifi, bluetooth, etc), that it is only doing around +800mAh in terms of charging the battery.

My Gnex charges at a little over 1000ma (with the samsung 1a charger - same charger that gives my nexus 4 ~850ma)
Nexus 5 got 1070 max with its' 1.2a charger.... both messured with battery monitor widget.
Could the N4 charge be limitted to 900ma?
Any chance my connetcor or battery need fixing?
anybody has any idea what could be the problam?
So i flashed a custom rom just yesterday and since then I have been noticing a huge increase in charging time of my device. It is taking twice as long to reach a full charge.
Idea is to share how much time it takes on your device to reach a full charge with what rom and kernel!
Happy posting
I'm on ihackers 2.1.
I'm charging with N7 charger (Asus charger)
Input 100 240 V
Output 5.0 V -- 2.0 A
Model AD83501
This charger charge Z1 in 45-60 min (from 5%-100%)
Using stock charger it needs 1,5h to do same thing.

Something doesn't quite add up there, either the asus supply is providing more than 2a (10W) or your battery isn't getting fully charged (calibration is off)
The Z1 has a 3Ah (3.8V) battery, which is at least 11.4Wh.
With 100% efficiency (no heat generated during charging and device off) you would only be able to charge the battery 87.77% in 1 hour.
It is possible at the kernal level to specify max charging current so a custom kernal may have a lower charging rate to preserve the battery, if the rom uses a stock kernal then something might be draining the battery whilst on charge (google / data sync etc)

Let me check that one more time.
I'll charge it tomorrow again and will check exact time.
What I wrote isn't 100% correct, it's around 60min.
But you are right - that is strange.
I never thought about that, it could be more minutes or really, it doesn't charge to 100%.

strange..mine one took around 2 hrs 30 min to fully charge from 10-100% using stock charger....
Last week I've installed a new usb port for my S4, because the old one broke. I know you will most likely think I've connected it poorly or whatever, but I don't think so, because I've had the slow charging issue before that.
I've got a couple of chargers. A Xiaomi 10.400 mAh charger, the original samsung AC charger, my nexus 7 charger, a Chromecast charger and a generic one from some store. The Xiaomi charger used to charge my phone quite fast. While playing Clash of Clans, on middle-high brightness I would still get about 1% every 2 minutes or so. Same with the nexus 7 one.
Right now however, it's struggling to get charged. It seems like the battery is draining faster than it's charging. But I've recently rooted my phone and installed the 5.0 GPE version rom, and my battery life has never been better. Recently got to 12h with about 2-3h SOT and still 60% left, which made me really happy. But if I charge it and use it, I only get about 1% every 10-15 minutes. Which kinda sucks.. (Right now, my s4 is on 87% and according to the lockscreen prediction thingy, it takes 1h06min to get to 100, while not using the phone)
Has anyone seen this problem before or knows how to fix it?
Do you charge it at your PC/Laptop?
My phone also charged very slowly when connected to the PC.. This was on original firmware.
Now I'm using GPE ROM but I haven't charged it at a PC yet.
There are some options in the Googy Max settings regarding charging.
What if it's the battery?

Nope, I charge it using a wallplug.
I must say it seems like my Xiaomi battery is charging my phone faster today. This afternoon it did about 30% an hour or something.
Edit: What it seems to be doing is charge fast at lower % battery, and charge slow on higher %. Is this a setting of something, perhaps?

I have an app called battery doctor which has 3 charging stages. From X% to 80% theres a fast charge, then from 80% to 100% it (supposedly) reduces the current to ensure a full charge (basically it charges slower from 80 to 100%). I don't know what difference there is in charging time in those 2 stages. But you say it happens on different roms so either you have recently installed an app like battery doctor or it's something else.
Have you tried charging the phone while it's turned off to see if it charges faster or same as before?

The only apps with root acces I have are system tuner, titanium backup and adaway. I uninstalled System Tuner, will see if that helps. And the only other thing that could do it is Googy-Max Stweaks.
I just turned the setting Charge Control Switch from disabled to Substitute AC to USB and got 7 % in 14 min. I feel it's quite a bit faster now. Gonna check it out while having Clash of Clans running. If it's still charging at 1% every 5 minutes, ill be happy
Just tested it for a bit, and went from 45 to 60% in 22 minutes. So I'm happy again
My battery drains too fast, using my phone continually it can discharge in about 3 hours. I have installed FirstFlight N7 Themed V6 ROM and I feel the battery discharges faster than in the stock rom did. I installed Ampere app to measure how much current my phone was charging and discharging and when the charger is not plugged in it discharges at 460mA, is that normal? I bought a Samsung 2A charger and it charges at 600mA or maximum 700mA but I changed the usb cable of the charger and it charges at 860mA or maximum 900mA. I don't understand because it should charge at 1900mA but it doesn't, how does I reach that? I need to mentioned that I charge the pone directly in a wall, not in a usb port, and why does my battery drain too fast? I need help :crying:
Charging current is dynamic. You can't make it always 1900mA as it highly depends on current device status, USB cable used when charging, etc. Also, ported ROMs tend to drain more battery compared to stock one and it's normal and not an issue for those who enjoyed ported ROM.

I was looking for modules to enable quick charge for Mi A1, but all I found was the mistake Xiaomi made during Oreo beta. Is there any modules to enable quick charge for Mi A1, or someone to develop a module using magisk? I've installed Magisk Manager to install Gcam, that's what made me curious. Correct me if I'm wrong in any statement!
Quick charge is generally not a good idea because it lowers the lifespan of the li-ion battery. The stock 10W (2A) charger will charge the battery at 1.5C rate which is already above the recommended standard 1C.
If you are referring to the Qualcomm's Quick charge technology... No.... Except for the obvious kernel and android changes there are also several hardware changes that need to be done for it to be enabled. Also given that 625 is with QC3 you won't really notice that much of a decrease of charging time. We still have pretty good charging times and given that the battery is only 3K it is really not that much of a deal. In the end you'll have 10-15min faster charging. Also at the end of the charging cycle (around 90%) QC is lowered to an ordinary charging, so for small batteries like ours it doesn't really have that much of a use. Also given that our battery is not easily changeable, QC and all types of faster charging lowers the lifespan of the battery significantly and it can go down in less than two years. If it is subjected to regular higher temperatures(>40 degrees Celsius it will start to form copper inside of the battery and will increase its self discharge significantly) it will go down in an less than an year.
Some custom kernels - like moun kernel - have fast charge enabled.
Speed up is not rly high.

Thanks, I'll look into it!
Quick Charge cannot be enabled( or shouldn't be ) on MI A1
Firstly let me clarify, I'm using RR ROM which has Moun Kernel by default, it has USB Fast Charge which is not to be confused with Qcom Quick Charge because it means it will Fast Charge( @10watts ) when on USB, that is plugged on a computer. On Stock ROM it charges very slowly when on USB.
Talking about Qcom Quick Charge, though sd 625 supports it, other hardware such as the battery isnt built to support higher voltages which can potentially damage the phone.
So no Quick Charge on MI A1

MiA1 has 3000mAh and supplied [email protected] charger gives 2A only! (I actually do get 2A charging up to 80% SoC).
Therefore, the MiA1 charging is at 2/3 = 0.67C and NOT 1.5C as you state.
For 0.67C, the time for 70% charging is 0.70/0.67 = 1.045hr = 63mins, which I'm getting in practice.
For 1.5C, 70% charging will be in 0.70/1.5 = 28mins!! Not just possible. Nobody, who tried fast charging using higher than 10W charger, has reported anywhere except slight decrease in charging time (for 70% charge).
The LiPo Battery in MiA1 is BN31. There may be a max charging current limitation circuit in BN31. I read somewhere (lost the reference, unable to find again) that 2.2A is the max limit.
In that case we get 0.73C and time for 70% charge will be 0.7/0.73 = 58mins. This HAS been reported using [email protected] at 3A. (BN31 allowing only 2.2A).
Add on Update:
There is one report on slightly faster charging of BN31. The max charging current is estimated to be 2.485A that is at 0.828C.
MiA1 got 0-100% charged in 92mins using One Plus' Dash Charger (not the charger provided which charges at 0.67). This is reported by TelecomTalk.
This is 24% faster than normal.

You're right that the stock charging rate is 0.67C which is a very moderate charging rate. No idea why the battery still heats up noticeably sometimes during charging. There was a change in the charging icon I think for the Oreo update which gave the erroneous impression that fast charging (>10W) was supported and people started (wrongly) reporting decreased charging times fueling the myth.
