CurrentWidget to ensure fully charged battery

So most people should have heard about currentwidget by now, most people talk about it and use it to see what battery drain occurs during standby mode or airplane mode.
Now I'm sure most know this but incase you didn't, currentwidget helps to ensure your battery is fully charged as well. This is good for people that complain about their battery dropping quickly after a full charge.
You can use currentwidget to monitor your charge, when the battery says its 100% and led is green, currentwidget still shows power going to the battery in form of "ma". I noticed my battery said it was charged and eventho at 100%, currentwidget still showed "ma" is being delivered to the battery . After two hours only it showed 0ma, now I'm sure that means that eventho my phone said its charged, it wasn't fully charged until 0ma were displayed in currentwidget. Since I noticed that, I've been charging my battery "fully" and did notice my battery stayed much longer in the 90-100% aisle when being unplugged.
So if you feel ur battery drops too quickly from a full charge, use this widget to help monitor your charge.

yep, tnx for the tip, im useing clarus battery and its do the same - and i like the widigt so...

the current widget always shows some value of mA . how do we know when the battery is really full ?

Well with me after 1hour at 100%, it shows 0ma. That's when I know the battery is completely full and reached its maximum capacity.

I don't think waiting for the battery to get to the 0mA level is good for the battery performance. Usually the green LED comes on when the widget shows 50mA.
A high-charge concentration for a long time in a Li-Ion battery is bad for the battery. Thats why mobile phones have a little buffer to stop the entire capacity to be full, and try to lose the first part of the full charge as fast as possible.

Since i use some RC Helicopter with li-po/li-ion that both have the same way to produce energy, I have learned how to use this kind of battery and how to ensure a good battery life/durability.
There is no reason to worry about the battery if you follow those few recommendation (given by a battery producer):
-Your battery has to be charged with a current of 1C max (1C mean 1230mA for a 1230mAh capacity).
-Your battery voltage must not be over 4250mV. If you go over, you may damage the battery and risk random explosion/fire. In normal use, it's better to not go over 4200mV.
If you charge the battery with your phone, you will never be able to go over 4200mV because the charge stop automatically before.
-Your battery must not be under 3300mV. Same risk as above. In normal use, it is better to not go under 3450-3500mV to ensure a good battery durability (numbers of cycle charge/decharge). I think the phone show 0% at near of 3450mV, but never check this cause i never wait my phone to be as close to the death.
-Your battery has to be drain at a current of 10C max, i.e for desire HD , 12.30A (1230mAh x 10).
impossible to reach that current with your smartphone so no worries about burning your cpu with heavy bench.
Whatever you do respecting this will not be harmful for your battery.

battery calibration improves battery?

I know android has issues with correct battery calibration but I am wondering if the belief of people is right in that calibration improves battery life. I think calibration is supposed to let you see the true level of your battery at a particular time?
OR am I wrong?

You're right, it doesnt improve battery

Calibrating your battery (if done properly) brings up your battery life upto spec IMO... It's no myth.

The battery won't get better with the capacility or so, it will just use the full battery if it is calibrated right
Lol my english

I believe that with 10 or 20 charge system calibrates the battery too without erasing batterystats

as far as i know, battery calibration is really required for all devices that uses lithium ion batteries.
that is because, the usual notion that in order to preserve your battery life, you need to charge it only if its fully drained is only true for ni-cad and older rechargeable batteries, and is not true for lithium ion.
lithium ion needs to have a constant cell charge (cells are what makes up your battery inside) . meaning it would damage your battery if you drain it to 0%.
now this process of constantly keeping your battery charged, sometimes would confuse the battery's configuration (as lithium ion batteries actually have their own CPU boards inside them that acts as protection). now in order to correct that confusion, battery calibration is required once in 30days.
the calibration process is draining your battery till it turns itself off then charging to 100% while the device is turned off.
head over here for an explanation.

^^What he said!

Battery stats wipe them and your phone will restart the stats from zero .
Dont wipe battery stats and phone takes about two weeks to normalize battery stats ..
Wipe battery stats only required after flashing new rom .

[Q] Weird Issue, phone auto shutdown when the battery is like 5% on Lollipop ?

My XT1092, recently got updated to Lollipop i.e. Android 5.0
Two of my battery runs, starting from 100% full charge came down to like 5% and the phone shut down automatically as if it was 0%
Also on a side note, i did not put any mode on the battery saver mode for those two runs.
Now to test it, i kept my battery saver to start at 5% but i am not sure if it will run at 5% or just shut down
Anyone got an idea/solution for this issue ??
P.S. Even Motorola care chat, does not have an answer, all they said is to keep my phone in safe mode for a day and check it out....

Mine just did this the other day. When I pressed the power button it showed the battery with a little red fill and a huge yellow triangle with an exclamation mark in it. Also happened last night.

I have also had the same issue xt1092 and on lollipop.

well...
yea man, so the thing is motorola support said that, keep ur phone in safe mode for a day and recheck the issue...
so idk... :/
i am checking my battery use and for now i have kept my battery saver on 5% so i hope it starts on battery saver itself.. rather than shutting down...

My XT1095 does the same thing. Really annoying! Its really lying to you about how much battery is left if its going to do that. I just know that if i'm going below 10% i better run to find a charger ASAP!

it is quite misleading to say the least..
i did not have this issue with KitKat though..
might be a lollipop thing only

I'll join this list. Really annoying, and never happened on 4.4.4

I've never let my battery get that low honestly, but...
Keep in mind that your battery percentage is completely an estimate. Battery capacity is measured in mAh, but there's no way to measure the current charge capacity in mAh of a battery. The only way to do so would be to run all of the power out of the battery and record the power over time, but then you'd have a dead battery. As a result, the system estimates your remaining battery capacity as a percentage based on the current voltage of the battery. But that can be different depending upon how quickly you've drained the battery and other factors.

So, Android has methods built-in which automatically calibrate the battery, but they only work properly if you fully charge and discharge your device on a regular basis. A battery starts off weak, then it gains strength after a few charging cycles, finally over time it peaks and then begins to taper off as far as battery life goes.
You've likely not taken your device to 0% for a while. The android solution is to fully discharge and recharge your battery a few times to allow it to recalibrate. Slow charging is the best for recalibration. Plug it into a computer for 500mAh charging rather than using a charger. Chargers can charge quicker(1.5A) but do not allow the device to calibrate as well due to the high amperage.
So, just use your device and let it drain fully, and charge fully on a computer USB port and it should recalibrate itself.

While it does help the calibration, it's very bad for your battery to do this deep discharge multiple times.

Sometimes you don't have a choice about letting battery drain get that far.
But regardless, its most definitely an issue with lollipop. Uncountable android devices, and this is the first time I've ever experienced this issue. Happens religiously at 5%. So its never happened before on any device I've used, including this moto x pure on KitKat, and it always happens at 5%.
If it were a true calibration issue, one would think it'd happen at different percentages. However I'm certain this is a bug.

I understand that you don't always have a choice, I just meant that I have no insight as to the possible bug since I've never experienced it. And to clarify, it's not really a "calibration" issue, it's a matter of there is no way to accurately measure the charge of the battery.
Honestly, Google could have even implemented this intentionally in order to prevent damage to the battery from a deep discharge.

But android has been completely accurate in the past. Right down to 1 single percent.
And there's no way google implemented this as a safety feature. If they were legitimately trying to do this, they'd just have the battery monitor read less than actual capacity as to not confuse the operator.
As well as they have what they believed to be a big feature, "battery saver" which has the option to activate at 5%. So them killing your phone at 5% intentionally doesn't hold water.

No it hasn't. It may not have shut down until after it read 1%, but it has not been accurate because there is no accurate way to measure the current charge of a battery.
http://batteryuniversity.com/learn/article/how_to_measure_state_of_charge
The fact that it consistently shuts down at 5% does seem like a bug, but it's a very odd bug since it seems like there would have to be some code to specifically tell the phone to shut down.

Every android device I've owned, probably 12, including the 3 still in service with me (moto x before lollipop, nexus 7, nexus 4) all have accurate battery meters right down to 1%. Now are they adjusting on the fly and lowering/raising battery percent to accurately match calculations? Probably. But it adjusts to where the battery meter will read down to the very last percent. No surprises.
The whole point of this thread us that some moto x pures are shutting down at 5%. Maybe the battery really is at 0%, maybe its at 5 or 10%, but its a "bug" that the phone is shutting off at 5%. Its rather a flaw in on the fly calculations where its not accurately adjusting at lower percentages, or a software flaw. But it's a bug either way. That's the complaint here.

Wrong. this is the recommended way to use every mobile phone battery. A full charge and discharge is called a cycle, and cycles are how battery lives are rated.

Please don't just post "wrong" without anything to back it up.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Table 2 provides details as to why what I said is correct. A 50% discharge will not degrade to 70% capacity for 3-4x as many cycles as a 100% discharge. That amounts to up to double the useful life of the battery assuming your usage stays the same.

Mobile device batteries are designed to be "fully" depleted. They are software controlled. You will never discharge a properly controlled battery 100%. This is why your device still has power to turn on and tell you that the battery is too low to turn on.
There are always exceptions to the rule. However, mainstream devices will almost always keep the battery at a safe level.
You cannot use a single chart on all lithium ion batteries. In fact, every one is different due to chemical and annode/cathode changes. This is why every battery has its own MDS for shipping purposes.
The small changes to batteries cause them to react differently to different usage patterns. When designing a battery these reaction patterns are supposed to be accounted for in the battery calibration.
A key engineering principal: a device should never be capable of destroying itself. Full discharge is normal operation for most devices.

battery capity? photo

So when i had note 8 after battery replacement i installed accubattery to see how battery health was. I see 2982. Now i fully charged to 100% with fast charge about 1 week every day. So i see now 3324! But real battery capity 3300. How recharged battery? When charged via normal charged usb not fast adapter, i have fast charge and i can disabled via settings. So on another phone i charged without fast charfe so i had 2430mah when reached to 100 it dropped down to 2400mah. Because slow charged and full reached charger. Sometimes i charged until 86% so increase mah battery. But on note8 i see overchargerdd on another phone i wiped cache accubaterry so when i turned on battery to see how battery left mah shows 2572 when i insert to charge the phone . So accubattery bugs?! Now shows on a8 normal! 2410mah 79%battery left health

Use aida64, its more accurate. To check battery cycle, use devcheck.

Devcheck shows 9 charge cycle but not shows how battery health

9-10 cycle shows that you really got new battery. Just check their capacity with aida64. You should get arround
3100-3200 on android pie when you fully charge it.

Yes the battery was new . When i got i installed accubattery app to see how much health left when insert new battery! Shows 98% now i charged a day about 2weeks to 100 with fast charger and without fast cable. Sometimes percent in accubatery app dropped down . But now shows 3331 mah 101%!!! I charging to 100% but the procent dont dropped down . Proceng should be down about -500mah when charged to 100. On another phone when i charged to 100% i see dropped -500mah. When i charged to 80% battery health extended! But on note8. Overcharged 3323?? Actually 3300 mah. But why shows accubattery 3323? I charged fully when i got new battery. And now still charging to 100 on every day!

My battery discharged in 10 hours with 7% brightness . Sometimes i used 4g. Screen on time 5hours a day. Normal? Nfc off ,location off. I trying with power safe mode!

Screnshoot your full charge battery capacity with aida64, we will knows exactly how much it is. Accu battery is base on observation, not directly by battery reading.
I got 600+ cycle and 3139 mAh, but still got 6-7 hour SOT usage.

Question How to check battery cycles?

Hi, is there any way to check battery cycles of my Zenfone 8?
I tried typing *#*#6485#*#* but nothing happens apart from this code disappearing from the dialer.

Grab the Accubattery app from the Play Store

Or GSam Battery

@MadDogMaddux , @M1chiel Thanks for your replies.
I installed these apps but I can't see an option to check battery cycle count since the very beginning of the phone life. Could you show me where is it located?
And the reason of this thread is that I bought used phone and I want to figure out how the previous user was using it and how much the battery is worn.

Gsam battery only starts collecting data from the moment it was installed.

Yup, you need to run it through a few charge cycles to verify.
AccuBattery will also help you see how much wear each of your charge cycles is putting on the battery, allowing you to significantly extend battery life through judicious charging habits (more, shorter charging cycles, rather than just leaving it plugged in overnight).
I'm attaching a screenie from my Zenfone, which I bought used in "very good" condition. As you can see, after 24 charging cycles it has measured about 12% wear on the battery. I'm a bit disappointed, but I scored a 12gb RAM/256gb HD model for less that $600US, so I'm not whining overmuch.
Anyway, you'll need to run a handful of charge cycles before the measurements will be accurate.
Anytime I buy off of Swappa, I ask the seller to run a few charge cycles after installing AccuBattery and send me a screenshot. Some do, some don't. ¯\_(ツ)_/¯
