[PSA] First Charge out of box is important for battery init

For those that experience long first charges, the first-charge charging time MAY be intentional.
I couldn't figure out why USB-500mA was taking so long to charge my phone, and wondered if the charging circuit wasn't correctly detecting the current rating (500mA) of my computer's USB. Charging shouldn't have taken more than 5 hours.
It took 20.
I'm getting ~>6hr screen on time now/charge and USB-500mA charging is snappy-- 3-5 hours or so. (albiet turned off all syncs except contacts and a few apps, app quarantine on facebook/drive/etc, and calibrated Lux for indoor lighting at 13-15% up to 150 Lux or so; and 1% for 0 Lux (at night); and Faux123's 003b3 kernel clocked at 1.6ghz and EcoMode and Snake Charmer ON in FauxClock (faux kernel control app).
TL;DR: the charging circuit wants the first charge to be slow. Don't worry if it takes long. It won't always take this long. Just for the first charge.

firstly, the first time you go to plug in your phone to charge is not the first time it has been charged. it has been turned on and off multiple times during production. also, i don't know about you but my phone came charged 90%. how did that happen?
secondly, it's extremely improbable that extra circuitry was put in place to limit the charge rate just for the the first time charge. if for whatever reason they wanted to limit the first charge, it would be done in production with production equipment.
which brings me to my last point...what is the benefit of rate limiting the first charge cycle?

TL;DR
Phone normally charges at 1.2A, you feed it 0.5A it's going to take more than twice as long to charge.
Simples....

hmm good thoughts. My phone came at 45%, which is right in line with what you should store a Lithium cell at, hence the start of my theory. Presumably, the cells get partially charged at the factory or are simply made that way-- have to be, because they won't recharge if they drop below 2.9-3v or so, charge has to start somewhere. 90%, probably not made that way though.
I doubt they have a lineup of USB-micro chargers at a dust/lint-free factory doing the charging for us, which lends credence to the notion they are _installed_ charged/factory conditioned.
Factory testing, would probably only take 15 minutes on the phone, if they even test everything (probably just basic stuff).
extra circuitry-- nothing extra physically besides the charging chip, the charging circuit for lithiums requires ability to sense charge current, because that's how you know when to stop charging (i.e. all lithium chargers have to be intelligent). So then you simply have to have a single 3-state flash or eeprom byte that starts at FF (programmed from chip factory), is initialized once to 0 on powerup in the chip (not android or even firmware, lower) code iff it's FF, and then gets written to "1" after the charging circuit gets shut off.
first charge cycle-- because if I thought they were doing it, I could see why they would (chemically). I guess they're not, so maybe I can't anymore. In theory, I could see why it COULD be good, something along the lines of running the car hard the first 1500 miles to ensure the piston seals wear/bed properly to the cylinder.

Charging through USB to your computer is always slower though. It was not intended to make the first charge slower and your battery results are mostly a result of your customizations.

Just a warning to anyone reading this thread... ALL OF THE CHARGING INFORMATION IN THE OP IS COMPLETELY UNTRUE
It really makes no difference how you charge the phone, especially so for the first charge. The phone's systems will detect when the battery is at full capacity and stop charging as necessary. So nonsense like the OP makes absolutely no difference, as it simply stops charging once it reaches 100%. The reason your phone charged slow, is simply that USB provides (as has already been said), a much reduced current compared with the wall-socket chargers.

You are comparing mechanical and chemical things here. like comparing wind and wave. Both can push things but driving force is absolutely different.

hmm..
im getting 5.5-6 hours screen on time without charging it at all when i just got it. and its first charge took just under 3 hours.

nope, not completely untrue just mostly untrue.
I take most of it back though.
It's possible the ultra long charge was because I didn't have a SIM in, constantly running radio looking for service?

The engine burn in is an old wives tale as well. The engines are all tested at high rpm the same as transmission before final assembly. No need to drive hard when it is new unless you want your transmission to learn your aggressive shift patterns!

Not having a SIM in wouldn't cause that effect. It'll still be connected to a network, as it has to allow emergency calls, it simply won't be allowing you to make/receive any calls/data/texts. It was just a slow charge as it was over USB, rather than the full power chargers.

but nothing else explains a 20h charge. That's 10000mAh at 500mA/hr (USB). I checked the CPU state and it was 300mhz the whole time-- same as every night. Except now, it only takes 3-5hrs to charge (on the same 500mA usb slow charging)
maybe the battery did need conditioning... - .-

To be honest (and I don't mean to sound rude here, just explaining my thinking), I don't really believe that happened. It seems highly unlikely, and goes against pretty much everything about the way the batteries work. This is assumign the USB port was actually putting out the full 500 mA, and that the phone wasn't having any kind of extra drain at all (which wouldn't be that unusual on a new phone).
Even if for some strange reason the battery did take an exceptionally long first charge, it was just a random occurrence probably due to a minor error in your battery. That doesn't mean that all first charges will or need to take that long.

really? that's weird. why do they say the exact opposite in the service manual (stay under 4k RPMs for the first 5-10k miles) if they've already broken it in? I saw some pics on a site from a guy who had people send him their 200k mile pistons and compared between those given the hard drive from day 1 vs. the soft drive break in method per manuf. spec. Those that were driven hard on purpose for the first 500 miles or so still had immaculate piston seals and zero carbon blowby/leakage. Maybe he was cherry picking results but the theory sounded good-- why else would they cross bore the cylinder? Might as well drive hard to help the piston seal as well!

of you are using your device when plugged into the usb, many times itll drain more battery juice than will be brought in. there are even live wallpapers that you can have running while plugged into tbe usb, and watch the battery drain right before your eyes. plus each usb device thst you have it plugged into could charge the device differently, some barely let a trickle in.

well, I will say that I can swear it happened because I plugged it in at ~8pm and it wasn't done the next day till like 5pm or something.
Only remaining theory (this actually makes sense more I think about it), is perhaps got confused and thought I was on USB 100mA. I was using a semi flakey USB cable that sometimes seem to have trouble detecting my phone is attached in Windows. Maybe that's what it was.
Additionally, the next day my battery exhibited some very peculiar discharge curves. After using for >5m screen on and turning the screen off, the battery % would rise about 3-5%. Additionally, I think I managed about 7 hours screen on time after that charge lending credence to my theory that slower charge curves store more energy.
Hm. I think I will try this again.

GPS fix problems

Since update to android 7.0 Miui 8 global 7.1.19 beta (via OTA) im having problems with getting a quick gps fix, i get the fix after some time (around 10 minutes) and then next time same. Is there any app to speed up gps fix ?

try this post: https://forum.xda-developers.com/mi-5/help/gps-issues-t3539327?nocache=1
advice1: it's a beta, use it with with a grain of salt.
advice2: sometimes a reboot will get you out of the mud.

Have you tried this?
https://www.xda-developers.com/gps-lock-faster-xdatv/
I usually use FasterGPS and seems to work fine.

not rooted so i think second option wont work for me. first option gets a fix after a while, but doesnt seem permanent, next time i start navigation i still have to wait around 5 minutes before fix

thanx for the answers though, guess ill have to wait for fix in update

If I am in the car and the charger is plugged in a GPS fix is 50/50. Even when it locks on it can drop easily.
The moment I unplug the charger GPS works absolutely 100% within seconds. Which is fine - as long as the journey isn't too long.

It happens to me too but only with a Quick Charge charger. It never happens when using other chargers or a non Quick Charge port (the charger has 2 non QC and 1 QC port). I'm going to test other cables just in case...

Sorry, yes forgot to mention that. It does appear to be an issue with Quick Chargers. AS you say, when it is plugged into a normal charger there are no issues.

Droid Turbo turns off automatically

Hi guys,
My phone turns off automatically. It actually has happened 4 -5 times in 3 days. Let me explain; Once my phone was just on my table and I picked up but it was off and nothing was happening. I just plugged in my wall charger (Turbo Power), it turned on and the charging showed 53℅ so it came back to life. Today, my phone was on charge and it was almost 70℅ andI had to remove the charger but as soon as I removed it, screen turned off and then I had to put the wall charger again to make it alive.
What could be the issue? I am confused.
Thanks!

Attached is an image of my battery stats for reference. Thanks!

82% wifi battery drain? Do you still have this problem if you keep wifi off? I would perform a factory reset if I were you.

Yes, the issue is still there when I keep my WiFi off. Also, i noticed that my phone used to get charge from 5℅ to around 40℅ within 15 or 20 minutes. I did put my phone on charge few hours ago but in one hour it was only 53℅.
I use Turbo Power wall charger and I purchased this phone 2 weeks ago. I'm not sure if doing factory reset would work or not but first I want to make sure there is nothing else wrong with this.
Any thoughts?

If a factory reset doesn't fix it, my only other guess is that there is something wrong with the battery. If you purchased it new, it's very easy to get a warranty replacement through Motorola if you live in the USA, but I'm not sure how it would work outside of it.

I just posted in the "Weird Battery" thread. But you need to do a Battery Re-calibration by holding the power button to turn the phone and KEEP holding button until the phone re-boots itself. Ignore the "Power Off" dialog. Then plug in the stock turbo charger overnight. I had this problem a lot while using a wireless charger.

Thanks for the response and I will definitely try this. However, there is something I noticed: Today I plugged in my Turbo Charger and the phone started charging from 4%. After 45 minutes, it was 22%. I think that means it wasn't turbo charging and as soon as I plugged out the cable from my phone, it turned off and again I had to plug the cable in and it turned on and started charging. I then turned on my phone and the battery was at 22% (charging). After next 30 minutes it was at around 70% and then I tried to pull out the charging cable to see if it turns off again but it didn't.
I am not sure if it's right but I feel like when it doesn't get a turbo charge, it gets turned off when I remove the charging cable from it. But when it actually gets turbo charge, it doesn't turn off and act normally.
This is really confusing, isn't it?

No one?

The most likely problem is that your battery is failing due to age.
Although it appears to maintain a usable voltage, reflected in the battery % displayed, it can no longer provide the current needed to run the phone under high-load conditions. In those cases the voltage drops momentarily below the 0% level, triggering an immediate shutdown.
Try taking the back cover off the phone and seeing if the battery is significantly swollen or bloated. If so, it's time for a replacement. There are good video guides on YouTube detailing the process.
Your device is two years old, and all batteries wear out with enough charge/discharge cycles. If the phone is exposed to high temperatures (such as during turbo charging), the batteries will wear out faster.

Are you sure it can be a problem of battery? I purchased this phone in start of February and it's new. Also, if it's a battery problem then why does it happen just sometimes? Why not every time i plug in the charger? Also, my battery after full charge give me a handsome backup of 1 and a half day easily even after 81% use of a WiFi.

A weak battery is one possibility, but if you're getting a day and a half of usage from a full battery, then it's probably a different problem.
My next guess would be a bad charging cable or damaged USB port. Or possibly a poorly written app that's running in the background and causing memory problems somehow.
What Android version or ROM is on your phone, what background apps are running, and do you have any root programs or system modifications?

Thanks for the response. My Android version is 6.0.1 and in background I am not sure where to look at but the usual stuff I use are Facebook, Watsapp, MyCafe game (I have already tried uninstalling it to see if it's causing the problem). My device is not rooted and there are no modification. I am using this phone as I got it new. Thanks!

For few days it was working fine. Now, I was facing the same issue again so I tried to do a factory reset. Now when I tried to boot it up for the first time, I was setting up the Google Account, I didn't remember my password so I first changed it using my PC and then tried to sign in on my phone but now it's always saying "please sign in using one of the owners accounts for this device". I tried to google it but all of it ended up giving me a solution that I have to wait 72 hours because there has been some Google Security or something? I don't understand. Please help!

sounds to me like the battery is dying/dead. i would certainly open up an inquiry to motorola to see if they can get you a new battery. doesn't hurt to ask.

I had to encrypt the device and it's back to life now. But still, the issue is still there. The phone still shuts down automatically as soon as I take off the charger. It's weird that when I don't face this problem, I get day and a half battery backup which is totally normal to me. Do you think it still can be a bad battery problem?

Hi Sh-Obaid!
Although this is a pretty old post, but I have just faced the same problem with my droid turbo as you were facing exactly a year ago. I am pretty sure that you must have ditched the droid turbo by now, but still I am curious to know if you finally found out the actual problem or some solution. Please share your experience as it can help me to fix my paperweight (almost dyeing turbo).
It keeps turning off during boot-up or android running mode within a few minutes after the charger is removed. But, it can stay 'on' for several hours in recovery mode (due to which I doubt that battery is dyeing) and also shows Good Battery status in the boot-loader mode. I have done factory reset and even re-installation of the stock rom but neither worked for me.
Any input from you would be highly appreciated - Thanks!

charging problem

I'm facing issue with my Rog 2, my phone is not charging fast
1. I'm using 18w charger come with the phone to charge
2. I have used Xiaomi 2i power bank with 18w output to charge my phone (still not working)
3. I restart the phone on charging it goes down 36% to 29%
4. On charging when i restart the phone it goes 8% to 13%
5. I'm facing this problem from the yesterday
6. Double plus sign on battery icon as well as fast charging text on home screen is also not showing while charging
What is the issue please help anyone

Though I may be wrong, I think you need the 30W charger for that. 6,000mAh battery is quite a handful and 18W may not juice it up as fast as you want.

Well, there is obviously a problem.
There are battery apps that can monitor incoming charge though not as effective as the hardware for monitoring charge but it'll give you a fair idea if you check it out.
I think you should reach out to Asus for solutions if possible, a replacement unit.
All the best.

I am facing this problem.This is rom problem?

FYI you can check the arrows in the battery icon when charging. 2 arrows means full speed - I guess -

Don't know if that's helps, I heard once that if charging percentage jumps in blink of an eye, then it's probably its need to collaborate battery mah with phone and it's done by dischargng your device by using it tell the phone goes to 0 and shut down it selfs , then charge it to 100% fully ..
Another app to see how fast your device being charged it's : accubattery , this is so far best option , but this app for analysis not for always use because it's consume battery like all other app

Battery/Charging issue

Hey everyone, how y'all doing?
I've got this problem for 2 months now where the charging has been super slow and no idea why. I am using the official charger and cable that came with the phone, I used my wife's s20's charger with same result and a third party charger with 3 different cables with similar results. Accubattery recorded that my phone's battery health is at 86% (3460mah) should I change it and lose my water/splash proof?
Oh yes I have flashed a few different ROMs (currently using Dr Ketan) with the same results except for evolution ROM, with the aosp ROM I was able to charge my phone from 14 percent to 100 in 90 minutes which is kinda weird...
Any advice would really help thank you

Get yourself one of those 2$ USB doctors. It will tell you how much power the phone is taking in. i.e. Fast charge should be 9 volts at about .8 amps and slow charge 5 volts at 1.5+ Amps.
Make sure your port is clean and moisture levels are low i.e should be below 80%.
I had this problem once when moisture was over 80%. It then went away. But at that time the phone will warn you about the extra moisture. It will say Moisture detected in USB port Fast Charging disabled.
The second time this happened was after the update to android 10. Had slow charging and overheating and audio acting up but that went away after re-setting the phone a few times and clearing cache.
The latest update to Android 10 seems to be causing a lot of issues with Display, Audio and overheating / slow charging. My audio chip finally stopped working. And the phone is now with Samsung.
My 2 cents if you see overheating and slow charging. Stop using the phone while its still working and take it to Samsung. Because if you continue to use it something will fail. And Samsung will want to give you a big fat bill to change it.

Thanks for the advice and I'll see to it. It's just yeah it seems like after android 10 things have been degraded

So apparently turning off fast charging in options gives me a faster charge time. With fast charge on it takes from 7% to 100% in 3 and a half hours and with fast charge off it takes 2 hours only.... Maybe my fast charging "chip" / "module" is broke?

Have you tried installing the stock OS back onto your device?

Yes I have tried, the June update one and got the same results. I even formatted everything and went bone stock with the same results. I'm thinking of using some contact cleaner on the usb port but hesitant to do that...

Unless you see something in there I do not advise poking around inside.
I suspect your problem is that the Samsung USB cable packed up. And your trying with all kinds of cables and chargers. Go to a Samsung Store and ask them to check with a Samsung Cable and Charger.
I went thru this circus a few months back.
The only solution is to get a Samsung Charger with a Samsung Cable.
Then make sure fast charge is on. For wireless and wired charging. Wipe your cache and you should be ok.
I have seen way too many damaged USB ports from people trying to clean it. When there was nothing in there to start with. Use compressed air. If you see something in there.
