Post Your Battery Performance

Alot of people seem to be saying their phones drain the battery too fast. I wouldn't know because I don't have anything to compare against. Figured I would post it here so others could compare...
Method: Left phone on charger overnight, took off charger and immediately rebooted phone. (Status showed 98% after reboot) Did not reboot or charge phone at all during the day.
Eight and a half hours later...

I consider this plenty of battery life. I had numerous chances to put my phone on the charger and didn't do it because I was testing it.

Ill check mine tomorrow and get back with you after a full charge tonight. I have a charger at work i plug my phone into whenever i am not listening to Music because i have to use the USB => 3.55 jack.

that seems like a really low voltage... aren't the G1 batteries rated at 3.7v?
EDIT: sorry i didn't notice the battery level was at 9 and 25... that seems about right, I was looking at the battery scale and got really confused.
mine goes almost up to 4200mV (~4198 if i remember correctly) when fully charged on the charger. It drops to somewhere between 4000-4100 when I disconnect though.
I am running the 1400mAh seido battery, but pretty sure the stock HTC one did the same.
For a lower bound, I think about 3.5V (3500mV) is where the 0% cutoff is for me.
One key thing to battery life many people overlook is signal strength. I worked in a building earlier this year with really bad signal (0-1 bar) and my battery would drain like CRAZY because my phone would search for signal the whole day. I verified this using the Watts app and battery drain during the mornings and evenings was significantly less than the hours I was at work. I started to keep my phone on airplane mode at work since I barely got signal anyway and it helped tremendously.

here's my battery info anyway after about 12 hours of 2g, no data (t-mobile killed the web2go apn ) a few texts and phone calls.

Anybody having problems with longer than usual charging times, as in it takes forever to charge, today I connected it to the charger at 80%, an hour later it was only at 86%

yes that happens to me as of lately but what i do is i reboot the phone and to my surprise is charged all the way after reboot.

lately i've been saving alot of battery power using "toggle data" app to turn off 3g/edge whenever im not using the phone, just flick it on when i need to and flick it off before i put it in my pocket, I work at an airport so while I may have plenty of outlet's to utilize I don't necessarily want to leave my phone unattended where shady ****er's can thief my ****.
cant give precise levels, but usually recharge to 100% overnight and by 6pm i'm somewhere between 30-50% depending on how much i've been able to us the phone inbetween actual work, and that's from about 7am, while that's not too bad G1 wise it still sucks cell phone wise heh.
also I found turning off the data while chargin definitely helps.
the G1 "phones home" every 5-7min when data is on which is why the data can drain on ur batrery and digg into ur pocket if your abroad w/ roaming on

Seems like there are way too many variables to reach any reasonable conclusion IMO.

hey.. how are you guys getting this information from? Is this a application? or where do I find this information so I can post and possibly help out. Thanx a lot guys

i will say that the best way i have found to get the "most" out of a full charge is to do the following...
Let phone charge up to 100%, for instance, overnight or whatever...
Then, power off phone...when you power it off, make sure that the red LED turns green indicating a full charge...sometimes even after a 100% charge, when you power it off it still needs to charge a little more
Now, power it on and you will have effectively "synced" your battery level with what android reads. This is by far the best way i have found to get the most out of a charge

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 indicator problem - new insight?

(I'm running Darky v8, but iirc some other firmwares including official JPY have the same problem.)
A lot of people complain that their battery indicator falls in 96-99% immediately after unplugging the charger. In my case, despite recalibration, it drops randomly between 96 and 99%, depending on the mood I guess.
What I realized by using circular battery indicator included in the darky v8 ROM is that this indication error is due to incorrect battery voltage measurement. So the percentage is correct as such, but since it's calculated from the measured voltage which is incorrect, we have our results.
Anyway, in my case, voltage at the end of charge cycle is for example 4.25V (100%), and when I unplug the charger it drops to for example 4.1V (97%) (those are just rough numbers, don't remember them exactly; just try it yourself). Yesterday I watched it closely, and after around 20-25 seconds of unplugging, it climbed BACK to around 4.17V (around 98%). After that it discharged normally.
It's highly surprising to me that voltage should jump up, even if it isn't so odd that it would suddenly drop when unplugging the charger.
All of this doesn't bother me a lot (although it would be nice to have 99-100% charge for at least a little while), but I wanted to point it out in case anyone wanted look deeper in the problem.

The higher voltage during charging is normal, that's how the charger works ) You have to provide more power than the phone needs in order to charge the battery. However, the battery meter should take this into consideration when displaying the battery's charge state. So there's your problem

It depends upon the indicator used Darky used circle indicator a while back and that was 98% .
My current indicators uses Quick Settings and ZD Box both show 100% .
Rumour has it that the battery is meant to read lower >

[Q] Just bought my Moto X. Question about the first time charge.

So, the salesperson told me to fully use the current charge on the phone and then told me to charge it for 6 hours straight.
Now the 30% battery it had lasted for quite a while I fully discharged it, it turned off on its own.
Now it's been charging for 3 hours and it's already full. Should I leave it for the full 6 hours? or can I use it now?
I'm a bit anxious but I can wait if its better for the phone.
Thanks :laugh:

You're gonna get different answers with no scientific backing.
So here's the first: just do an extra 45 mins to an hour after it reaches 100%.
If you click the link in my sig and scroll to the bottom of that post you'll see my battery life which, is pretty decent.

Thanks

Thanks man

This is sheer non sense. Once the phone reaches 100 percent, the kernel cuts off the charging . What use would it be by charging it for another 45 hrs?

I second this. Charging batteries had specific charging instructions years ago, that no longer holds true. Just charge the phone and use it. it's not that big a deal.

It's just for calibrating the battery.
Let me just get this out of the way: most of the time it doesn't make a difference.
The only time it could (not always) make a difference is one of the following scenarios:
-phone sat for a long time while turned off (i.e before you purchase it)
-you hooked up your phone to the charger many times throughout one day and didn't allow it to hit 98-100% before you unplugged.
The battery has a chip built in [most lithium ion batteries have this because they are A) explosive and B) can kill you] which is responsable for a few things:
-"guessing" your current battery percentage based on the minimum and maximum recorded voltage value. For example let's assume a phone with a 5v battery shuts off at 3v. When that battery reaches 4v it will display 50% battery left.
-deciding what the shutoff voltage is. What I mean by this is let's say for example when your 5v battery reaches 3v at the end of the day, the chip decides it's time to shut off the phone and prompt you to charge it back to 5v
-constantly reading the the voltage in order to use that data to perform the decisions listed above
The voltage sensors in phones are, well, pretty bad due to the inherent space and power limitations. The voltage values swing back and forth between different values that are (sometimes) close to the actual value the battery is at. So the battery chip has to calculate an average based on all these voltage values. It then uses that data to do it's job, which is shutting down your phone when it needs to as well as display battery percentage.
So by leaving the phone in for a little longer after 100% once in a while, all you're doing is allowing the battery chip to collect more voltage readings in order to calculate the average more accurately. You're just doing it for the sake of sample size.
Realistically unless your battery is not calibrated, it doesn't really make a difference. But a phone that just came out of a sealed box is likely to need calibration depending on the manufacture date, or how long it "sat" for.

It may cut off charging..
But on my X (Dev for Verizon, stock and rooted), even after reaching 100%, the battery symbol still continues to show the "lightning bolt"/charging symbol. If I leave it connected to my Anker Astro 3, it continues to draw power until I unplug it.
@MrEndless, I agree with DaRkRhiNe and scorpion667. You're never going to get a straight answer.
Me, I ran mine down until the phone shut itself off, then charged it up to 100% and left it go over night and took it off the charger in the morning.
Once every few weeks, i do the same. Run it down until it shuts off and then put it on the charger and let it go until its been at 100% for a while. I never really say "xx minutes" or "xx hours" after 100%. It just depends on how long before I have to leave the house.

Modify expected battery capacity (charge larger capacity then original)

(TL;DR at end)
Hello,
I have been comparing aftermarket batteries with larger capacitys then the original battery (findings will be shared when finished testing).
I have come across a problem where the phone shows 100% charge on a larger capacity battery, when not actually full (does charge till actually full, but shows 100% for large part of it).
Looking for -
help to somehow fix this. Show actual larger battery charge precentege. I'm hoping this is something we can change, as in expected battery capacity, software.
Avidance -
1. Charging while off, indication of fully charged (screen changes from 100% & charging icon to ✓ icon), only after around another 1.25 hours of charging [for the original battery, this takes around 25 minutes].
2. When off and showing charging 100% icon - larger capacity battery at 3.87V. Reaching ✓ icon - battery at 4.2V (measuring with physical externel tools).
Etc.
[Seems larger capacity is being used when discharging truly fully charged larger battery (lasted in test up to 1.3 hours more then original).]
3T, OOS 9.0.6, rooted, Xposed
Example from different phone (needed file to mod not on 3T) - https://forum.xda-developers.com/s7-edge/help/mod-aftermarket-misreading-battery-t3510597
I'd really appriciate some help on the matter.
When finished with my research, I'll post my findings (looks promising - found up to 30% increase in battery life!)
TL;DR - Testing larger capacity batteries. Problem of them reaching 100% when there is more charging to do. Phone charges what's left, but shows 100% all the while. Looking for a fix.
