Charge time for the Inspire 4G

I haven't seen this anywhere else on these forums, so i figured i'd post this potentially useful info. Using the stock AC charger that comes with the inspire in conjunction with the Current Widget App, i have been recording the time it takes to charge the inspire over a variety of start conditions. I consider 100% full when current widget reports 0mA charging. I then took that data and plotted it with a corresponding trend line. There is of course a bit of variance due to any given percentage being associated with a range of current values, but the formula listed will give you a surprisingly precise ETA to charge your phone to full from any given start point. I hope this is somewhat useful.

FYI -
As you can see from the graph, there is a significant discontinuity from the zero point near 100% charge. This is due to the fact that i am using Current Widget to monitor when no more current is being delivered to the battery, coupled with a decreased current delivery from the Inspire 4G at higher battery percentages. This is a built in safety feature to slowly "top off" the battery near maximum to prevent damage to the battery from excess charge.
Basically, just because your phone says 100%, doesn't mean that it's completely, and totally, full of charge. The current widget shows the Inspire continue to charge (non-zero numbers) for about an HOUR after hitting 100%.
So if you simply want to see 99 or 100% in the display, subtract an hour from the charge time. IE, the formula would be TimeToCharge ~= -2.122*(current battery percent)+240.

[Q] 4.2.1 Battery Drain Issues?

Hi guys, I've flashed the 4.2.1 ROM by albinoman887 and only when the screen is on the lowest brightness it uses a lot of battery, really quickly.
Thread can be found here
When it's on standby the battery lasts for about 7 hours, but when it's on it lasts for around 45 minutes. Please help
I've tried
- Wiping battery stats
- Calibrating battery.

Your horrible cell signal is at least part of the problem. Your phone is constantly pinging the towers looking for a better connection. That's a serious battery hog.
You may have the wrong radio for your carrier. Or you may live in a dead zone for your carrier.
Also, is this your first battery cycle after a full wipe? I get results like that for the first discharge cycle after install. But then it becomes fantastic. Drain the battery all the way until the phone shuts off. Then charge it using a USB cord on your computer (not the standard power charger) for an hour past when it says 'full'. The slower USB charge can help to give it accurate voltage readings while charging so it doesn't stop charging too early. See if that helps.
The battery on Albino's 4.2.1 is pretty spectacular for most people, so the good news is that this is probably a fixable issue on your end.

The signal was when I'm out and about, most of the time I have 3-4 bars on HSDPA, I may do a full 24 hour charge or get a new battery

I have this problem too.But if i flash last build,baterry life is good.

[Q] Battery stats are completely crazy

I have this problem for two days now, the battery stats gone completely crazy and has lost total reference of the actual level.
The 100% level is something like actual 50%(based on voltage levels) and it stays at 1% for the most of the battery life.
The phone does not turn off until the battery is completely depleted and when charging it still goes charging after reaching 100%(I can see this by the voltage indication).
Since the battery is 3.8V, full charge is about 4250 mV and empty is something about 3400 mV, but still my indicator is wrong and I don't know why.
Wiping battery stats didn't work and I don't know how to fix this. Does anybody has some clue?
I'm considering writing my own battery level indicator that uses voltage levels(based on discharge profile and temperature).
Here are some images of my problem.

Do you regularly let the phone die/turn itself off before putting it on the charger? That can sometimes help reset these lithium ion batteries.

nomittai pleased
Sad Panda I had to do that a couple of times.
I've also encountered a problem when fully charging the battery, since the full charge was wrong the battery would not get over 3,8V.
In order to solve that you need to wipe the battery stats when it says is 100% and it's important to leave the charger on(voltage levels are higher this ways and is the key for solving the problem).
After that unplug the charger and reboot the phone the battery will be on lower level on the indicator, repeat this until you get 4235 mV without the charger or 4350 mV with it.
When real full charge is achieved it takes 2 full charge/discharge cycles to reset the battery to normal. Here is important to make shure the battery is 100% and don't charge until it turn off.

External battery - the differences in power and charging time

Hi everyone,
Looking for an external battery to the phone I9505 Galaxy S4. I found two that I liked, but I'm trying to figure out if I can use them for galaxy i9505.
It's about 2 batteries, which look identical (as shown below), but differ in capacity and power input:

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Code:
Capacity: 3200mAh
Input: DC 5V / 800mAh
Output: DC 5V / 800mAh
Charging Time: 3H
Cycle Life: 500 times
Code:
Capacity: 4500mAh
Input: DC5V / 500mA
Output: DC5V / 800mA
Charging Time: 8 hours
Cycle Life: 500 times
If any input power may cause problems?
The second thing.. I found on many pages that these batteries are designed for models I9500 - the point is.. if you take a percentage of these models, eg on ebay only 1/10 was an indication of the model I9505. Is it safe to use both batteries?
The third issue is whether it is true that the longer (slower) the battery was charged, the greater lifetime retains ?
I appreciate any advice.
Best regards

You aren't going to notice a difference in life cycles at those charging rates. Batteries have shorter life cycles when charged at very high amperage, like in cars.
I think the bodies are all the same.

How charge Mate 8 normally instead of quick charge?

Hi.
There was a (little big) charger inside phone box and there is " HUAWEI QUICK CHARGE " label on it.
When I charge my phone with this charger it will get hot and fully charge takes about 45 min.
Now how can I have a normal charge instead of quick charge?
I couldn't find any option in the phone to switch between normal charge and quick charge.
Here some details of the charger:

Thanks.

"When I charge my phone with this charger it will get hot and fully charge takes less that 40 min."
This of course is completely impossible

Any way, how can I charge my phone normally?

Just use a normal wall charger, I'm using my old LG charger while charging at night ... you don't need to set quickcharge or something else ...

Or use a crappy usb-cable. Or simply keep on using Fast Charge, which doesn't overheat the phone, here, at all.

So there isn't any problem if I charge Mate 8 with my Xperia Sp or other charger? (OUTPUT : 5.0 VDC - 850mA)
Why there isn't an option to switch between normal and quick charge? (That's too bad).

No, there's no problem when using a different charger.
Why do you want an option? I dont understand ... what would be the benefit of such an option?

Quick charger would damage battery in long usage, wouldn't it?

nope

OK.
Thanks.
