FP5 - Battery Life

Hi all,

I thought I should post my observations since my FP5 upgraded to Android 14. I tend to charge my phone overnight, and before the update, I also had to charge at least once during the day, but I still found that the battery was almost dead by the time it was plugged in again.

Post update things couldn’t be more different. I only charge once per day, even if I’ve been using the device heavily. I regularly still have 60% left at the end of the day!

I was beginning to doubt my goal of making this phone last for up to ten years, but now I’m more convinced that It’ll be possible :slight_smile:

Did you use “always show date and time” aka AoD?

Btw I moved your post here

Nope - I turned that off when I couldn’t last a day :slight_smile:

I’ve noticed it only lasts about 6 hours as of lately. I don’t know what’s running in the background. The only things I use is AVG security, cleaner, VPN, iTech wearables, and Fitbit in the background. But still I used to get 8-10 hours of use. Now it drops from 100 to more around 30 to 20 percent in a matter of hours depending on the workload i put on it. Only 2 hours if im gaming. But watching video or music is about 4-6 hours respectively. It seems that it hasn’t lasted as long daily driving this phone with the Android 14 update. Further degrading the battery in the process. This info comes from experience just using the device daily. It may be different for your usage of your device.

Sorry to say that but you might be overkilling your battery by charging it daily to 100 percent.

No.‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎

Hi, is your way of saying there’s no consequences of running a full cycle every day if one can use half a cycle by cutting some of the higher percentages? @Nabalazs

The batteries are said to last a finite number of cycles.

Sorry, I will elaborate.
The rated charge cycles of a given battery, is calculated with the assumption that it will be charged form 0 to 100%.
Therefore, no extra degradation should occur when someone tops up their phone to 100% every night. It is the intended use case of the battery. Your comment makes it sound like they are doing harm by charging to max every night. Nothing will be “overkilled” if you do that.

The heaviest degradation occurs roughly between 80-100% charge. So if you regularly only discharge to 80%, then plug in to go back to 100, that might accelerate the degradation noticeably.

And in reverse, you can go the extra mile to only ever charge from 0-80% which should slow down the degradation.

But under normal circumstances, a user shouldn’t be faulted for charging their battery to 100% routinely.

Thank you @Nabalazs , that’s a perfect explanation.

In hindsight my comment was too brief and exaggerated. The batteries used in a standard form should still last from 300-500 cycles. But if one uses them this way, could they not expect some form of degradation after the year? Perhaps this is what @Digimon has been describing.

Yes im aware that charging to 100% can ruin the battery. I agree with you Meaghan. However it should still hold a decent charge after a year or so of use. Thats what i mentioned in my post. Latlely it has almost run dry with only a few hours of use. Im also aware of the charge cycles and do let it get close to zero before charging monthly. This is the same for all batteries regardless of use. Also if your not planning on using the device for a while. You should run it down to like 5% battery before putting the device away. This makes it last longer and most people don’t usually do this with tech in general. The only company changing the cycle rule is Apple and their iPhone 15 with about 1,500 cycles instead of the usual 500. Still as a daily driver of FP5. Charging it to 80 percent and then using it lasted half as long as i needed it to. I used that mode for a month and my use case was about the same as it is now. It seems to not last the amount of time I need it to today. I might switch back to 80% mode and charge it more often. It just means more time on the charger. Charging it once a day isn’t working anymore anyways. The only other thing is I disabled fast charging to protect the battery about a month after i got the device. People were experiencing problems with that enabled. So I left that disabled. Hope that this corrects the misunderstanding of my previous post.

Small correction: batteries should be stored long term at roughly 50% charge. They don’t like being neither at max charge, nor run dry, long term.
Don’t know if that’s a typo or not. But it should be 50%

Technically it really depends on how long you plan on storing the battery. If you plan on comming back in a few months then its 50% charge. I ment 5% for one reason. Most devices are left at 50% and causes the battery the expand and then more than likly explodes like the note 7 due to the amount of charge left in the battery. If you plan on storing it long term like years without use or a decent charge in between. Then its best to almost have it completely drained. This in tern saves the battey from becoming a ticking time bomb in your home. Thats a straight fact. Did you know that most devices are shipped with barely enough juice for this reason alone. Just enough to basically turn it on and get the battery indicator saying plug it in. I need to be charged. I have had plenty of devices say that when purchased brand new from the store. Its a good strategy if you plan on putting it in the attic or the basement for long term storage. Most people don’t honestly know that fact today. Only if you plan on using it again in like a few months do you keep that charge at 50%. Thats what im trying to say in my last comment.

And if you don’t plan to ever use this battery again it’s a good idea to discharge it to almost nothing. Then time and self-discharging will do the rest, the battery won’t be usable after some time anymore. But then you shouldn’t attempt to store the battery at all, then you could give it to disposal directly.

And to get back to the thread topic: I know how to “burn” my battery, too, but on normal days I get through with one charge (starting from 80%) and I’ll still be above 20% after 24 hours. Therefore, seeing a full charge being burned within 6 hours is somewhat unexpected to me. I’d really check what exactly the phone is busy with and see if you can do anything about this.

If I store the battery like i replied. I can always come back later to a game system to relive a memory. I have many portable game consoles that I would rather keep around to maybe reboot them later. I’ve made so many digital purchases on them that i would rather keep them around. They haven’t failed yet after multiple storage cycles. That’s the same for controllers with rechargable batteries. Storing the like this has never failed me. In fact It has more than likely saved them from failure in the long run. This all comes from experience of tech over the years. You can tell me if I’m wrong from wanting to preserve tech history from years gone by by this one image. (I just charged them all up from dead after all)… The GBA SP is A 23 year old battery, and still works to this very day. Something tells me what I’m doing is the right way to handle batteries in general.


Now about your issue. Mine set at 80% charge wiith fast charging disabled. I lost my six hours and am down to 4 hours before it needs to charge three times a day now. Before i got about 8-10 hours on a charge on Android 13. On Android 14 I have 6 hours from 100%. From 80% its four hours. I still say something else is running in the background taking up the extra energy resources. I came to the conclusion its the extra scanning feature introduced in Android 14 that scans every so often for threats. I think it does more in the background while using the phone. Thus taking up all the extra energy from the battery. This could be the cause of both of our problems.

You mean play protect? that is the one that scans for malware (actualy it just a blacklist by google)

you mean:

6hour from 100% to (ex.)10% ?
or 6hour ScreenOnTime?

Im referring to Antivirus programs are plain known to be resource hogs. No matter what you do. They still take away resources by running scans constantly. Anyone who had a PC in the 90’s with limited 512mb of ram can verify my statement. That’s why they are still considered “A Resource Hog”. Even if its in a different format or platform. In fact that’s why I still have AVG for both PC and all my phones. It may take away battery life. But it only takes a few hours. Take this info for what you think. Im still positive that this is also the issue by a few hours. Just another antivirus that take away resources by constantly running in the background.

In answer to my question, is Antivirus irelevant ;⁠-⁠)

Once again no. I use it every day. If its in settings. Then its there. Using my FP4 on Android 13 it lasts all day with it peroid. Im honest that this new feature will cause battery drain. Even if you don’t think so.this is not discussing vpn in all this. I use both programs and i can confirm a few hour loss on both android 13 and 14 with these apps installed. But it has lasted all day on an older version of Android. This is my point im trying to explain to you. Even if you dont want to admit it.

An update for you. I like the new battery menu in settings. The bad part is they got rid of the graph which indicates more time on the charger with this Android 14 update. Oh well here is your proof that my phone is currently having battery issues and it ain’t a year old. The only other thing i can’t explain is these settings process with security and privacy menu. I know this is the cause. I ran the same programs on my Fairphone 4 and it still lasts the whole day of use. I don’t have any other info regarding why its causing this than these screenshots. But having to charge it three times a day is basically impossible to use off the charger for more than three hours before that 15% notification tells you to plug it in. Basically becoming a paperweight on my shelf. Hope it helps this thread. P.S. I finally figured out how to capture the whole screen. It took two years to figure this out. LoL.
