Logging of services for battery saving? - G1 Q&A, Help & Troubleshooting

Hello,
I recently started using an application called Battery Graph that lets me see my battery usage over time, and I've noticed that if I were to leave the phone in standby that in 1-3 hour intervals there's a big 5-10% drop in battery charge. I was wondering if there were anyway to log what application or background service actives during a period of standby so I can find and disable whatever is leeching my battery life?

I'm sure theirs a hundred apps on the market, and if your running cyanogen, theres a nifty little tool in there somewhere that shows you what apps suck up what.
But honestly, I would suggest buying an extended battery ($16), I currently own one, and MAN, I can last all day and half of the next under full gaming/etc.
And I'm not exaggerating
(Besides the fact I just violated 2 of the most crucial grammatical rules by starting a sentence with 'but' or 'and' )

[Q] Battery drain issue?

Hey everyone,
I'm not sure if I have an issue with a defective Captivate or if it running as intended. That's why I've come to you guys for some insight.
Here's my scenario:
A few days ago, I decided to leave my Captivate off of the charger overnight to see how much battery I would awaken with. It was just a little experiment I thought of to see how much the battery drains while not having anything intensive to do (such as power a screen). I fully charged the Captivate to 100% before setting it on my desk and going to bed. As normally, everything was turned off except wi-fi. When I awoken the next day (8 hours of sleeping), to my surprise, my battery was down to 27%. I was shocked that something could have drained almost 70% of my battery overnight. I downloaded an app called Spare Parts as a recommendation by some people and I seen "Running 100%" which means that the phone spent no time sleeping. When I look at any partial wakelocks, it showed "Android System" as a full bar. I assume that it could be a bad app that was keeping my phone from sleeping.
I restarted the phone, battery pulled, charged up and uninstalled some apps. Everything seemed back to normal as when I checked the the running %, it was proportionate to how often I was using the phone (not at 100%). I specifically checked if the phone was sleeping and it was through some monitoring. I would use the phone for 1 minute and then let it sleep for 2 minutes and you could see that the running % went down, as it is suppose to.
I kept monitoring the running % over the course of the day and it was fine. The less I used it, the lower the % would go; the more I used it, the higher. I also monitored what kind of apps I was firing up and I specifically made it an effort to not open any apps that were out of the ordinary. If I did, I checked to see if it kept my phone from sleeping and it did not (through my same usage tests as above). However, even after my close monitoring, sometime during that day, my phone would stop sleeping once again. I could tell because my running % never lowered, no matter how long I didn't use my phone. It would keep climbing which means it no longer slept. I made sure that I didn't do anything out of the ordinary too as I used the same apps as I did when the phone was sleeping fine. I checked "Android System" and it was getting larger. The battery was around 80%.
I charged up the phone again to max and made sure that nothing was preventing my phone from sleeping. Did the tests again and running % was proportionate again and I double and tripled checked to make sure the phone slept. I then left the phone not charging again to see what would happen as I would have no interactions with the phone to open any apps or change any settings. To my surprise, my battery was down to 60% (~ 6 hours of sleeping) when I awoke. I checked the running % immediately in the morning and it was at a very high percentage. "Android System", once again, dominated the partial wakelock portion.
So what's going on here? It doesn't actually seem like I'm doing anything on the user end to prevent the phone from sleeping. How come it decides to act up all of a sudden? If it was a bad app, how come it decides to prevent sleeping all of a sudden and not before? Even if it was a bad app, I didn't even launch anything while sleeping. Does the phone decide all of a sudden to stop sleeping?
The apps I use are:
Tasker
Y5 Battery Saver
Launcher Pro Plus
Twitter
SwiftKey
NHL Gamecenter
Handcent SMS
doubleTwist
Dropbox
Does anyone have the same problem?
Any help is appreciated.
Get rid of any task killers and battery savers they do more harm then good and most developers recommend not using them, they cause battery drain. The only battery app I use is Juicedefender because it keeps the phone from connecting constantly and keeps apps from running in the backround. I set it to connect every 15 min for 1 minute to sync, I turned off all notifications because they annoy me and I don't need to be notified everytime I get an e-mail or someone posts on Twitter or FB. My battery life has improved greatly once I dumped task killer. Also, I am running a Froyo mod and my battery is amazing now and my GPS works.
If you are in an area with a weak signal this will kill your battery because your phone is constantly searching for a signal and trying to connect. Also turn off wifi if you are not near wifi this will save battery.
Also try calibrating your battery and bump charge it. Here is a link for that. http://forum.xda-developers.com/showthread.php?t=765656
The battery will improve, mine got better after a few weeks of break in. I am at 60% been unplugged since 10 am and I made plenty of calls, checked e-mails, sent e-mails, checked XDA developement all day and I have plenty of juice.
Good infos. O agree with not using task killer

Hmm, thanks for the tips but there still seems to be something lingering around in my system that doesn't allow the phone to sleep. It seems to activate all of a sudden as well without user intervention.
I again left it overnight and it drained again when I woke up. I lose significant battery overnight when I sleep. I'm thinking about just restoring to factory settings. I've only had the phone for a week so I wouldn't lose that much data. I'll monitor it from the onset once I factory reset it and see if it's a hardware defect or something that was bad in my phone.
Do you have a live wallpaper installed? Also, do you have a bunch of Widgets on your homescreen? Are you constantly synching with e mail, FB, etc? No doubt something is running all night. It's not the phone, it's something you have installed. I set mine to sleep with Juice defender at night so nothing syncs. Check your wireless bill to see how much data is being sent while you sleep. Why not charge your phone while you sleep?

Nope, no live wallpapers and the only widgets I have on my home screen are the LauncherPro Plus widgets, Smooth Calendar and BattStatt. The only syncing I have going on is Google Calendar and Gmail but both of those shouldn't cause the phone to not sleep.
I was thinking of using Juice Defender but I would rather just get to the root of whatever app is preventing my phone from sleeping and kill it at the root instead of finding workarounds. For all I know, my phone may not be sleeping not just overnight, but with normal use as well and it would adversely affect battery life throughout daily use. I need the piece of mind that my phone is properly sleeping.
And I have no issues with charging while I sleep, but again, I need to find the root cause. If for whatever reason I'm can't access a charger overnight in the future (such as if I sleep over at my gf's house), I want to know that I won't wake up with a dead battery in the morning.
I really appreciate the help though.
As for what I decided to do next, I actually factory restored my phone yesterday morning and so far it is working well. I did not download any apps at all to make sure that this problem didn't persist with a stock phone. If it did, I would know that it's a phone defect and not something I did. Throughout the next week, I'll be installing different apps one by one to see any one of those apps will cause my phone to not sleep. This will allow me to isolate the app. It's long and tedious, but I would go through it for better battery life. So far, it's been working as I'm already through 10 hours on my phone with moderate use and it's only at 50%. Whatever was destroying my battery before absolutely had an effect on my daily battery life as I would struggle to even get 10 hours on my phone with moderate use.
Same Here
I find your post very interesting. I have not yet used Juice defender, however, I am now more keen to battery drainage. I talked on the phone for about an hour the other day and my battery went from 100% to 40%. I find this unacceptable for a phone. Imagine taking conf. calls and conducting business in the field throughout the day. My battery would be dead in two hours without checking email
I hope you can reveal your findings to help us all.

JROCK
Battery problem fixed using the simple technique similar to the one shared back in this thread.
I used to lose 10% per hour (or there abouts) and by 5 or 6pm needed to go on charger. At the very best with no use it dropped 3-5% in an hour.
Now its all changed...
After being off the charger for 35 min and taken 2 calls and sent a couple of txts she still read 100%.
At 5hrs 17min off the charger it is at 81% and there has been 6 calls in total and about 9 txts, plus a couple of appointments added.
Here is what they said to do and it worked...
1. Charge the phone for 8 hours, but make sure it is turned on while charging.
2. Unplug the phone, turn it off, plug it back in for 1 hour.
3. Unplug it, turn it back on for 2 minutes, then plug it back in for 1 hr.
Then unplug and enjoy the new battery life
Sounds too easy to work, but bugger me, it did!
27% is clearly abnormal.
Sometimes, I put the phone on it's charger after a pull day only using 27%.
I read somewhere on XDA that some early phones had defective screens that would only shut the backlight off and not turn off completely. Don't remember what came of that thread though.
I have a battery drain issue as well. My Captivate is 2 days old and been charging it every night. The first charge was done via the computer while transferring music over. After moderate usage (1 hour of music, browsing apps, learning how to use the phone, etc.), the battery died after 10 hours. GPS, and bluetooth was turned off. WiFi was used for maybe 20 minutes. When I got home, I charged it overnight for around 10 hours.
Today, the phone died on me after 9 hours. I rooted via z4root and applied RyanZa's latest OneClickLagFix, which both apps can be found on the market. Before that time, the battery said there was about 80% remaining. Fast forward to 6 hours later and the battery is gone. Again, moderate usage.
According to *#*#4636#*#*, my Screen On is at around 60%. A few other bars are pretty high as well, but I'm not sure how to do a screenshot on the Captivate right now. The only method I found requires using a PC. Plus, my battery is dead meaning I have to charge it overnight again.
I had an issue for the last couple of days, just figured it out earlier today. I had a corrupt thumbnail file on the external SD so my android.process.media (something like that) was constantly running.
I first realized something was wrong before I determined the battery life was bad when I noticed that my CPU was constantly at 11470-1200mhz or 975-1000 when I disabled the OC.
Unmounting the card would allow the CPU to drop to under 200 at idle so I knew it had something to do with the external SD. Turned out there was a bad file under a DCIM (camera folder), so after I deleted it, it became smooth as silk!
Of course it's still an i9000 rom so battery life is still questionable

Sorry for the hijack!
Here are yesterday's results:
Does these results look normal to you? I'm particularly concerned about the Social Hub and screen, and running. They're all higher than I expected. The brightness of the screen is set pretty low, maybe 2/10 of the brightness bar. As for Social Hub, well all I got is the Facebook widget, which is set to sync every 4 hours. Other kinds of syncing is off. GPS is off too. I don't have any battery saving type of apps yet, except for RyanZa's OCLF which includes the WiFi timeout.
I ended up charging the phone at 5% battery left. I had to sleep!

Need help. Battery or Phone?

I have Motorola Bionic which I purchased few weeks ago and was having numerous problems. Phone getting HOT, No data or data connection dropping out of the blue, goes into sleep mode doesn't turn on or off unless I take out the battery and most importantly, my battery drains really fast. With Extended battery, the phone last about 4 hours under normal use and only about 5-6 hours on standby.. I don't think the problem is the battery since I have 4 EXTENDED batteries and 2 Standard batteries which I got from Verizon. Standard batteries last about 2-3 hours in normal use. I need 2+ extended batteries to get me through the day.
The other day, I called Verizon and they send me a replacement phone and so far, I don't have issues mentioned above expect for 2. 1. Phone still gets pretty warm but at least NOT hot but I am still having problems with my battery draining really fast. Its little better with the replacement phone but still it only lasts me 4-5 in normal use and 5-6 hours on standby. The reason I know that stand by last about 5-6 hours is that before I go to sleep, I put a new extend battery in and when I wake up, the battery is completely dead.
Due to the battery drain issues, I have made the following changes and it help but very little.
-Sync email every 1 hour except for Gmail which pushes the email. I have total of 3 emails on my phone including Gmail.
-Facebook is logged off so it won't sync.
-Twitter is logged off also.
I don't have any other data sync programs running constantly other than logging in to couple of financial data application through out the day.
Per Droid-Life, I heard that there was a small batch of Bionics that were manufactured with battery draining issue and numerous other problems which I think my first phone was but even my 2nd phone, battery is draining really fast. I don't think I am that unlucky to get 2 phones in a row that are defected.
Also, the funny thing is that even when the phone is NOT in use, 4G LTE shows data going back in forth constantly and I am not sure what is causing this. I think that's whats causing my battery to drain really fast even when not in use.
Any input or suggestions will be greatly appreciate it.
for it to lose signal like that and get really hot, it's having big time issues with the antenna and obtaining a signal. so something is wrong with your phone, not the battery.
get it exchanged.
Do a factory reset and don't install any apps. If it still drains it's the phone, if it doesn't it's an app causing it.
Settings->battery & data manager.
Tap the battery.
Is there an app or two at the top of that list?
Also, do you see the sync icon in the status bar all of the time (it looks like a circle made of two arrows pointing at each other's tails.) If so, you could have a sync loop (of your Google contacts or calendar, for example) or something.

Help with Battery Life

Hi guys, I'm worried about the battery life of my HTC One.
When the phone is on lock mode, meaning screen is off, within one hour battery can go down from 1-3%. Power saver is on, brightness is auto. And 4G/LTE is on.
Also, I only play around with my settings, checking out GSAM battery monitor, within 15 minutes battery can go down 1-2%.
Now it's been 6 hours 22 minutes since I unplugged from charger, battery level is 74%.
Is it normal?
Thanks.
Gsam should be able to tell you where your battery is being used and what app. Look at what the offending app is (most likely Google maps and Google+ or facebook) and use an app like greenify to hibernate them when not in use.

You do realize that the phone is still doing stuff when the screen is off, yes? Syncing e-mails/facebook/news stories, communicating the the network, etc. Even if the phone were completely off, lithium-ion batteries will still deplete(albeit very, very slowly) over time. 1-3% loss in an hour is pretty normal in standby. If you're really concerned about it, you can check out an app called BetterBatteryStats and it'll show you what's waking your phone up from sleep and/or preventing it from sleeping to help identify apps whos sync settings are too aggressive.
Your battery has depleted 26% in 6hrs 22minutes... you're losing roughly 4.08% per hour, at that rate it would take you ~24.5hrs to deplete the battery. Battery depletion is, can be, and should be accelerated when you're using the phone, so 1-2% within 15minutes while looking at a battery monitor... yeah. The more stuff you do with your phone, the sooner the battery will run out.
TL;DR: your battery life is fine.

Thanks for the info. However I noticed in some threads that for certain people, their HTC One can last for 1 days 9 hours. For example:

It's going to be very difficult for you to replicate the results of someone else(and we are lacking a ton of information from that post--is he running a custom rom, custom kernel, are screen off/on profiles being used, what apps are syncing, how often, how many, etc).
Beyond usage, phones can vary greatly from within the same model based on the manufacturing process/location/materials. For instance, there's a thread in the General Section exploring the differences in various HTC One's screen maximum screen brightness. Even down the chemistry of the batteries themselves. I know from personal experience that one of the biggest impacts on battery life can be how strong of a signal you're receiving from your carrier. If you life/work in a low signal area, the phone will increase power to the antennae to maintain the connection whereas if you're in a good signal area, it doesn't have to work as hard.
Anyone use GSAM Battery Monitor app? Why does the battery usage % doesn't add up to 100% when you add it with the remaining battery % sometime?
Yesterday it's still fine. But today my battery usage % + remaining battery % only add up to 93%.

Most people use that app. I'm not sure why it isn't working 100%. Did you plug your phone in for a very short amount of time? That might make errors. After you charge it overnight everything should be fine. Try using it for another day.
Sent from my HTC One
In GSAM Battery Monitor, my App Usage is always the highest contributor to battery usage, usually around 85%-90%. Screen is only 10.8%.
When I dig deeper into the App Usage, Kernel (Android OS) 23.8%, and Android System 15.7% are the top 2.
Is it normal?

Btw, do you know what is AsyncCollectorListener wakelocks that come from Maps? It also contributes to high partial wakelocks percentage most of the time.

Yay no more miscellaneous battery drain!

So, having noticed soooo many people report the reasonability of Google potentially hiding the "miscellaneous" battery drain and not actually having fixed the Lollipop battery bug on Nexus 5.
I did some calculations. I am guessing now that 1% drain in batt stats means at least 1% drain and not less.
We don't have 5 significant digits of battery drain. That would be perhaps too specific. Complete accuracy of battery drain for the seemingly simple entropy of heat dissipation would be astonishing too!
However,
I counted up an extra 1 % on sombunall drain counts, and got 47 rather than 36 percent loss. I mean some 1% drains were 1.4% right? Maybe 1.7 or 1.8... I don't know the rounding or truncating algorithm.
Then, I added 35% battery remaining and got 82% of my battery accounted for.
Then... I remembered that I used about 30 more apps and that many syncing apps and services and usages that did happen... were NOT EVEN in my battery stats.
Just assuming that some energy cannot by used in one form without transferring into another form (thanks Grade 9 lesson on conservation of energy!), I will assume every nanosecond of my app usage and syncing services ALL drained part of my battery, even if less than 1%. I wasn't using any magical crystals in my other pocket or anything.... THEREFORE,
I will conclude, only to indulge in hyperbole and be silly, that my phone has a maximum charge capacity of about 113%!!!!
Google's doing something right!!
Well, to be serious for a second, 30+ stat unmentioned apps each used LESS than 1% but must have used MORE than 0%.
Thus I am certain, about 100% of my battery stats makes sense on Lollipop, and NO MORE MISC BATT USAGE BUG!
Yay! Thanks for a decent product Google,
And for great ROMs and kernels all you developers!
You make things work better for people's activities and livelihoods.
W00t, 5 hours SoT, 26% battery left, 4 hours average use left for the day... That's sweet by all counts.
Yay!

New Z3C - Battery dissapointing

I just bought my Z3C a couple of days ago. First thing I did was charge it fully and then I started using it. It went from 100 to 0% in about 21 hours. During that time a SIM card was inserted only during the last couple of hours, but I did use the phone fairly often. The attached thumbnails show the details.
I did notice that it almost loses no charge in standby. But today I noticed an increased decline during screen on time after standby time. See last screenshot attached.
I expected more from this battery based on reviews and Sony's claims. Is this normal or is my battery faulty? While some here report similar numbers, others seems to get a lot more out of their batteries.

You shouldn't expect more from this battery based on reviews, you should just look at what some people got out of their phones.
Give the phone some time to settle in. And don't forget that it's almost summer for us now, more sun means using the screen at a higher brightness so that will also have some impact on your battery life.
Look what kind of useless apps are running in the background and stop them and don't worry about the estimate, it really doesn't mean much. Right now my estimate is 9 days, because I barely touched my phone.
I really don't believe in such a thing as faulty battery. Charge your phone, restart it and see how it reacts then.
Is Stamina mode enabled? If not, then what you have is typical. Getting a full day out of one charge is about all you can expect from a smartphone without some form of battery saving measures enabled.

Here are my results:
http://forum.xda-developers.com/showpost.php?p=59933232&postcount=48
At the moment I have 3d 10h battery life and still 40% left. Tomorrow after work @ 12 our time I'll charge my phone again, so that's almost 5 days.
(But that's with a lot of idle time)
(Vergeet geen apps te freezen en je telefoon te restarten)
With moderate usage, you should generally expect just about 2 full days of battery life from this phone. And that is with Stamina mode enabled to help the phone sleep when the screen is off. However, this is not accounting for any extreme measures some people take to extend their battery life (e.g. disabling background data/sync). Once you remove these features, you're no longer using the smartphone as it was intended, so it's not a fair comparison.
I can easily get 2 days out of my Z3C before I think about charging it. And I've never used Stamina Mode.
I guess I could install some app to monitor battery usage and stats but I'm not that bothered tbh.
We all manage a variation on the smartphone thing, in terms of data, wifi, gaming, emails, browsing, texts, calls, etc, and its slightly different, in terms of use, from one user to another.
I'd echo the sentiments of another user who said give your battery time to settle in. Give it a full charge, discharge cycle a couple of times, and don't worry too much about it!
Peace.
Thanks for your feedback, guys. I'm currently fully charging and discharging my battery. Several cycles complete.
The best result I've gotten so far is a little under two days with moderate usage and thorough measures to increase battery life. I turn on airplane mode when I go to sleep. Stamina mode is also enabled, but only the reduced performance part. I'm also using 2battery, which turns off WiFi and data when phone is in standby, and turns them back on briefly every 15 minutes. (While I agree that turning off data connections defeats the purpose of a smartphone, I also believe that there is no need for a constant connection when I'm not using my phone. 2battery achieves that. Although I must say it doesn't seem to kick in a lot on lollipop.)
So despite these measures my battery seems weak compared to yours. Anyway, I'll be taking your advice and I'll give it some more time.

I have like never used Stamina mode, try out these apps:
https://play.google.com/store/apps/details?id=com.rootuninstaller.batrsaver
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
You need to be rooted tho (Which shouldn't be a problem)
Are you using GPS or is it always on?
Your battery is fine. You probably lost some standby life when you put a SIM in it, as that would cause your cell radios to begin seeking your carrier's towers.
Do activate Stamina mode if you haven't already done so.

Thanks for the pointers! I have Better Battery Stats, and will give the other two a go. Sounds like DS Battery Saver goes beyond 2Battery, which just manages data and wifi. It can also kill apps, but I suppose you use Greenify for that?
I am indeed rooted. GPS is always on as far as I know. Haven't really paid attention to it. Why do you ask? Does that consume a lot of power?

Well yeah of course GPS uses a lot, especially when you don't use it, it's just wasted energy so to speak.
Greenify lets apps go to sleep earlier/faster so that they can cause less wakelocks.
With Greenify and DS BS I don't need Stamina mode and many of us are even wondering if Stamina is working most of the times, these two apps I'm certain that they work.

Well, I've been keeping an eye on it for the past week, and I seem to be losing next to no charge when screen is off. My phone is in deep sleep over 75% of the time. (According to Better Battery Stats)
I do seem to be losing 1% charge for every 3 minutes or so while my screen is on. Is that normal? We're not talking gaming or anything demanding, just some browsing and messaging.

I think the best way to measure if it's correct or not, to for example put some movies on your phone and let them play constantly, see how long your phone can manage.
You should get at least 6 hours of on screen time using that method
It's too late to say this, but after getting a new battery/phone you should always drain it fully and then fully charge the battery so that the battery has a proper charge (it saves a lot of battery capacity and battery life)

Good that it's too late, because it's incorrect. This suggestion dates back to the days of NiCd batteries which had "memory effect". Li-Ion batteries found in modern devices for at least the last several years and definitely since the beginning of Android don't have this effect, but have something else - when you drain the battery completely, you cause damage to the battery cells, and it can withstand only a few of these full-draining cycles before losing significant part of its charge capacity. This is why both laptops and phones have protective measures to turn off the phone completely before the battery reaches a dangerous drained state. And as the batteries go bad and their "low percentage" scale becomes unreliable (not able to sustain operation currents with low charge), these protective mechanisms can fire too late - which in turn can cause storage corruption to occur, if the power is lost gradually and not abruptly during operation.
To another poster that doesn't believe in faulty batteries - he better should. Batteries go bad with time and charge-discharge cycles, they're harmed by complete discharge, and can go bad in several other ways. However, I wouldn't expect a battery to start its life damaged - quality control of the manufacturer should prevent this.
My results for reference - I have ~2-3 hours a day SOT, 1-2 hours tethering, have several phone calls, messages and mails - and the phone is usually upwards of %50 at the evening. I have to run it through ~4 hours navigation to reduce it to sub-20% towards the end of the day, and actually see no reason why a smartphone should hold any longer - it's routinely recharged every night. The main problem for smartphones, to me, is not surviving till the end of the day.

Thank you for sharing, but that advice is about as outdated and useless as changing your car's oil every 3000 miles. Batteries simply don't work that way anymore and some studies show that battery life is actually reduced when you perform full charge cycles instead of shorter recharges throughout the day.
Edit: looks like someone else best me to it :-/

Actually sorry to break it to you, but you are wrong, Li-ION batteries do have a memory effect, since about 2013, researchers have found that they do have memory effect.

Well, thanks for showing me something new. However, this is a very different effect from NiCD. While in NiCD this effect would prevent the battery from taking a full charge when repeatedly not discharged fully, in the research you've showed there are 2 very important points:
1. What matters is not the discharge, but rather a charge. Charging not fully is a way to trigger this effect. On the other hand, discharging partially (like in NiCD) doesn't trigger it. This point makes the info, while indeed interesting by itself, irrelevant to the current discussion, and keeps your previous suggestion wrong and bad for the battery.
2. If kept charging a bit longer - the battery would still charge fully, though it would take a different amount of time from the expected. For night time charging, when the phone is connected to the charger for several hours more than it's needed to actually regain the charge, I'd guess that most of the time it does the job of filling the battery properly even after an incomplete charging cycle.
[edit]
After reading it again - actually there is a third point that makes your suggestion even much worse than I thought it is:
This memory effect that you've pointed to is triggered by having an incomplete charge followed by a complete discharge. That means, incomplete charge with incomplete discharge don't cause it - a complete discharge is required. And when you receive a new phone, the battery isn't fully charged - so if someone goes by your suggestion:

He would actually be triggering the memory effect you've linked to, on its bad side!
And just for reference, here is a recent article from 2015 that is far less technical, but does a great job of explaining battery behavior in practical terms that average people can understand:
