Hello! I am working on building an android phone (got a cheap Blu Dash Music C) solar powered server. I am working on the power system and an torn between several possible power options, and I guess it boils down to the following scenario:
What will happen if I root the phone and modify the "fast charge current" to 2000ma (or whatever the max rate the hardware allows) but the source is unable to supply that current? Will it just charge at whatever the available power rate is, or will this cause some issues which I have not thought of? I am thinking I will replace the phone's battery with a 20ah 3.7v (4p 5ah). If it would indeed be capable of charging at 2a, this would be perfect as:
- I could use all parts I have on hand, and use the phone itself as a charge controller.
- That would be similar my solar panels output (wattage)
- If power gets low, phone should power off like normal vs having to install some type of low voltage cutoff for an extrnal system.
But obviously as it gets dark power will drop off to zero.
Thoughts?
Thanks
P.S. Got this working reat with a Raspberry Pi and simple SLA battery but I believe an adroid phone will use less power overall and has 3G/4G built in.
Hello!
Is it possible to disable fast charging capability of LG V10 in its OS/software/firmware? If so, how? Solutions requiring root and/or xposed are acceptable; however, solutions requiring a custom rom aren't acceptable, because my device's bootloader is not unlockable.
Using a slow charger is not the solution I'm looking for.
Thank you for your help!
Question is, why would you want to charge your phone slower??
But to answer your question, you would need a custom kernel.

Hello Derek.
Thank you for your reply.
I wish to preserve the life of my battery for ecological, practical, and financial purposes.
If you're of the opinion that fast charging does not degrade the capacity of the battery, I welcome your arguments, comments, and sources.
Thank you, again.

Your battery won't accept anything more than what is intended. Your phone regulates how much power is used by the battery and also regulates how much power it is drawing from the charger. If you have a charger that's output is more than your battery input, your phone will regulate that to it's MAX input. If a charger has a lower output, well, you are just charging your phone slower. There's a reason they give you that charger and usb cable.

If you were to disable fast charging then you would be slow charging. Most if not all quick charge 2.0 chargers have the ability to "slow" charge devices. So a much safer option would be to just buy a charger that doesn't have quick charge. Instead of messing with the system files. Quick charger + disabled quick charge in phone = slow charging.
Just use a random non quick-charge charger. And don't worry about the cost of the replacement battery. It's like super cheap.
I agree with the last two post, just get another charger, and the battery is cheap to replace.
FYI, the charger that is supplied with the phone is not fully QC 2.0, it does not support 12V QC, only 5V and 9V.
For a while I was surprised that all of my quick charge 2.0/3.0 accessories were only pulling around 8W (9V @0.9A) when charging at any battery level (measured with a USB current meter). When I would plug into the original OEM charger, I would get upwards of 17-18W (9V @1.8-1.9A). When using "normal" USB ports the phone would pull around 7-8W (5V @1.5-1.6A). It was particularly surprising as these accessories work well on other QC 2.0/3.0 devices, and the Ultra was clearly negotiating 9V with the QC accessories but restricting the current pull.
Searching around, I finally found out that it seems that ASUS has locked down the quick charging to their own chargers:
http://forum.xda-developers.com/zenfone-3-deluxe/help/fast-charge-t3484970
http://wap.ithome.com/html/262150.htm
This is quite unfortunate for those of us who have a bunch of Quick Charge accessories that basically don't work at full speed for this phone, but even more frustrating that the phone is advertised as being QC 3.0 without any disclaimer that it really isn't because it locks out any non first-party QC 3.0 chargers to 8W or so.
The last link being in Chinese, Google Translated as follows:
9 months since the Samsung Note 7 listed since the battery accident can not help but let a lot of consumers on the phone fast charge technology security to be re-examined, according to users broke the news: earlier this month in Taiwan listed ASUS Zenfone3 Deluxe because of its starting Xiao Long 821 processor with 6 +256 memory settings by many consumers blitz.
However, some users buy the hand found that although the nominal mobile phone support 18W (9V2A) of the QC3.0 fast charge, but must use the original comes with the fast charge to open, and the remaining third-party charger can only 5V1A / 9V1A "Slow charge", even after Qualcomm certified QC3.0 charger can not fast charge, which is no doubt that those who pay attention to the speed of charging the user is very dissatisfied.
For security: ASUS Zenfone3 version of the exclusive use of non-exclusive use of fast charge
Some users complained that the online posting, said ASUS is currently not produced official QC3.0 mobile power and car charger, means out of the words Zenfone3 Deluxe can not use fast charge. ASUS official staff in the official website QA area and network forum to respond to said: the current fast-charging specifications are not uniform, the output voltage power is not the same, in order to avoid dangerous and unpredictable accidents, it is recommended to use the original charger charging. At the same time ASUS official also gives the original charger identification method:
1, only the nameplate with a lightning bolt (as shown in red box) of the ASUS charger to Zenfone 3 Deluxe and Zenfone 3 Ultra open QC3.0 fast charge, for security reasons if the use of non-ASUS original QC3.0 charger Will not open the QC3.0 fast charge mode;
For security: ASUS Zenfone3 version of the exclusive use of non-exclusive use of fast charge
2, using the original charger fast charge, the desktop battery icon will display a "+" number, while the bottom of the screen will display "fast charge" in the words.
For security: ASUS Zenfone3 version of the exclusive use of non-exclusive use of fast charge
Despite the matter in the network forum has caused no small response, in view of the current public opinion on the phone fast filling the skepticism, ASUS in various channels of the reply attitude is quite firm. There are users that buy their own official ASUS mobile power ZenPower Ultra Zenfone 3 Ultra can open 18W fast charge, the charging problem to be resolved temporarily.

I've bought a ZS550KL (5.5 Inch Zenfone 3 Deluxe) today, which supports QuickCharge also, I had a Zenfone 2 ZE551ML 4GB/64GB previously which also supported QuickCharge, and I can confirm that QuickCharge on the ZS550KL _only_ works with the supplied charger. Both the ZE551ML Zenfone 2 charger, as well as my third party QuickCharge charger do not work.
Also, and this is even more stupid, my ZenPower Pro, which supports QuickCharge too (and works flawlessly with the Zenfone 2), also does not work on the ZS550KL. This is a real pity, having QuickCharge especially on an external power bank is incredibly useful... besides, it's an ASUS product, IMO it should just work. Too bad ASUS doesn't even give us the option to override this behaviour (I wouldn't mind if it was hidden somewhere, but I just want it available).
Same problem here
The quickcharge compatibility was disabled with a certain update (I think it was the Android 7/N update). It should have general QC 3.0 compatibility with certain firmware versions. Any way to downgrade?
Can anyone confirm if these chargers are compatible with the rog 2? Planning on getting one.

It is interesting, but at the same time risky, if they are not compatible they can shorten the life over time, damage the battery indicating false reading on the phone, or the last thing burn you'r phone.
I would really like some hard info abou this topic!

Thankfully due to USB standards, plugging your phone into a charger that is capable of outputting more power than the phone is designed to use, will not damage the phone as it is not the charger that decides the speed that the phone will charge at, it is negotiated between the two devices and charging will start at the fastest speed that both of the devices support.
Due to Oppo's VOOC 2.0 being a proprietary standard that is only supported by select Oppo devices, if you connect any other device to the charger, it will just charge at whatever the maximum speed that can be negotiated between the two devices, which is most likely going to be 5V 2A (10W).

So since oppo owns realme it's probably using the same proprietary tech too. Bummer.
The question is whether you REALLY need those extra minutes shaved off of your charging time. Faster the charging, faster your battery deteriorates. Speaking of compatibility, I doubt you'll get anything above the 30W that Asus provides support for. I'd recommend you stick to the 18W/30W charger bundled inside, or a QC 4.0 charger.
Works fine with my old Huawei Superchargers (45W)

How faster is it compared to the stock charger?
Can I charge Xiaomi Note 10 Lite with a standard Samsung charger? Following are the specifications of chargers
Xiaomi Note 10 Lite came with 30w Fast Charger, following is whats written on the charger:
Output 5.0V=3.0A 15.0W/9.0V=3.0A 27.0W/12.0V=2.25A 27.0W/20.0V=1.35A 27.0W/10.0V=3.0A Max 30.0W Max
I want to use the following Samsung charger:
Output 5.0V=1.55A
I don't need fast charging and I am planning on keeping this phone for a longer period of time thus want to use a standard charger to save the battery.
Kindly if anyone has technical knowledge about these readings please advise me whether I can use the above standard charger without damaging the battery if not what standard charger should I buy for my phone?

Thank you but I asked the opposite, I want to charge the fast charging phone with a standard charger. The question was whether my specific charger with 5.0V = 1.55A be safe for my phone battery.
Also to add: the reason I mentioned the Volts and Amperage details is because I don't have much knowledge about it. I remember using a different charger (on laptop) with only slight differences and it caused the battery to bloat. So I need to be sure this Samsung charger won't harm Xiaomi's battery lol
Update: I have been charging 'Mi Note 10 lite' with Samsung Standard Charger (1.55A 5V) but the charger is getting too... hot, not sure whether its affecting battery life (battery is not getting hot) though.
