Spare Batteries. How fast will they drain when not in phone? - Galaxy S III Accessories

Hey, I just had a general question. I was thinking about picking up a two pack of Anker 2200mah batteries from ebay for $15. They will be used as spares, so I was thinking of leaving one in my car and the other at home. I was wondering if anyone would have an estimate on how fast the batteries drain when not in the phone? For example, I charge one of the spares to 100% and put in in my car (ignoring temperature fluctuation in the car), then two weeks later I am in need for the spare so I pop it into my GS3. What percent will the battery be at? Do you guys think it will be more than 95% after two weeks? one month?
Also, how much will temperature fluctuations in the car affect the drain? My car temp fluctuates from 45F to roughly 75F
Thanks

You should buy a set and test it out. Lol.
They don't discharge much. They do slowly. At the store, new phones have batteries that sat around. They are usually 25% - 50%. I charged a E4GT battery almost 3 weeks ago. Sat around, I turned it on and it said 90%+.

In my experience the temperature fluctuations are what cause the quickest drain. As awesome as the idea of leaving a spare in the car is, it's about the worst thing you can do to a battery as far as storage goes.
Sorry to rain on your parade, this is one of those "I hate reality" situations. If you could create a climate controlled storage area within the vehicle it wouldn't matter...
Make sure to run a charge through the battery at least once a month to keep the cells in good shape.

Yeah, you'd be better off just carrying one on you instead of leaving it in the car to bake. Get a man-purse!
I got one made of Chilean leather, and I get a lot of complements on it. I carry my S3 and all my other crap, including a data cable for USB charging. Doesn't weigh much, so I hardly notice it, but it sure comes in handy.

Sorry, I left mine in my computer room. No temp changes.

Mine stayed in the 90% if within a week or two. I alternate them so that they don't go bad and get a fresh charge here and there.

2x Battery + charger 2000mah($13.00)

Gonna try them out...not sure what i'm gonna get but for 13 bucks worth a try

Highly doubtful 2000ma batteries, probably 1500ma batteries that are really 1300ma. Tutoit on ebay I have 2x1500ma batteries for a 9.98$ shipped with a charger, I would get that instead.
yeah, either get the 2 1500s and the charger for 11 50

I was just looking at this... seems like a great idea... the extra charger allows you to keep a second battery charged without using the EVO to do it. Even if it's really a lower rated battery... still a good deal.
Did you try it?

I have a set of the 1500 mah batteries with the charger as was posted above, and I have no problem with them. I use my OEM battery most of the time, but sometimes it is handy to have some fully-charged back-ups. Honestly, I don't see much of a difference between what my OEM battery lasts and the knock-offs. For the price, you can't beat it.
so how are the batteries?
normally i would stay way from cheap Chinese crap on eBay, but with what i read here on the xda boards in regaurds t othe ok qualitybeing good enough that they might work out, so i ordered 2x1850 plus charger from ebay. i dont have time to do any real testing but i can say that:
1 not having to charge the battery from the phone is nice
2 i always have one on the charger, one in my pocket and one in the phone.
3 charging in the base seems to get me a better charge
4 i cant tell a difference between oem and knock offs, although you would think that the 1800's would last longer than the 1500oem but we know how that knock off crap goes. in my book if they are the same as oem, regardless as to what they claim and dont require a bigger back plate, then i guess that's good enough.
The 2 from tutoit or what ever the sellers name is work great last as long or longer then my stock battery. The charger also gives a better charge to the batteries then I get through my phone I'm talking extra hours when I charge with it.

I got this and it's a good deal for the price.
The batteries aren't as good as oem. Probably last 75-80% as long.
The charger works well though and it's nice to have a couple extra batts laying around. I've only cycled them 4 or 5 times so I suppose the life could improve...time will tell.

I Have a number of Minor issues with mine. Must of gotten a bad set.
1) USB port on the charger does not output enough juice to charge the phone (Accually Locks it up until I unplug it)
2) Charger seems hit or miss on recharging the Stock Battery. I've left it plugged in all night and come back to ~20% charge when I pop it in a number of times
3) Random Screen cut off when charging the Replacements IN the phone.
So I only charge the Ghetto batteries in the charger provided.
That being said, I STILL think it's a great deal and more than happy with my purchase. I have 2 spare batteries for my phone (Or the wifes CDMA Hero) and a way to charge one w/o having to leave my phone behind (I don't have to babysit my phone for a charge, If someone walks out of the poker room or party with my charger and battery it's no big deal) The 2 China batts. are just emergency tanks, The Red one gets put back in as soon as I get home.
Best Purchase at twice the price.
Don't wait press the BUY NOW!!!!
Loved the first set so much that I purchased a second set 2 weeks later. I keep 1 set at work and 1 set at home. I always carrying a fully charged battery in plastic bag in my pocket. I love the EVO but hate the battery life. The first month I owned the EVO was hell for me having to carry a power charger and cable everywhere. I hated having to plug my phone in every time I found a power outlet worried if I didn't I may find myself without a phone when I needed it or having to fight everyone at the airports for power outlets. Now when I'm low on juice, I just switch batteries.... BUY NOW you'll never regret it....
I purchased 2 3500 batteries with new backs on e-bay for $22 and change. They work great I can go for over a day with fairly heavy usage.
Only minor problem was that with the phone thicker my silicone case doesn't fit as good. Extra weight no problem.
Yeah one thing I have learned from buying these types of batteries and charger is that they don't like to charge the OEM batteries but charge the cheapo ones just fine. I've noticed it on alot of things not just phone batteries.
buy it for the charger
i bought a 2000mAh that turned out to be a 900mAh so i would only buy it for the charger.
I wouldn't recommend the 2 x 1500 batteries plus charters the 1500's seem like a 1300 or a little less I would say try get the 1800 one from eBay they have a lot of auctions for them so all you gotta do is be patient and try to get for cheap that's what I'm tryin to do
Just ordered one of the 1800mah.. will see how this works out!

3500mah battery

I cheaped out and got a 10 dollar Ebay extended battery.
I thought I would report my experience. I cleared battery stats and it's now charging.
Typically during my normal work day by the time I get home the battery has about 10% or less . That's usually about 13 hours off the charger. I typically just surf the net, but I also text, play games and watch videos.
The first thing I noticed was the increase in weight. The extra bulk hasn't bothered me yet. When seeing new phones the slim ones look so much more desirable but with the width of the evo the extra thickness isn't super noticeable when actually using the phone. I'll see how I feels in the pocket. Being shallow it does look about 65% uglier though.
I will take pictures later.

Cool, I want to get this but I heard some things about the phone not able to charge all the way with the 3500. Can you please verify? Also, please go into detail about the usage and your stats have so many hours please!
Interesting I just woke up and got a phone call. Lasted about 2 minutes and then I used the browser to navigate to your post. After reading it checked the charge level and it's at 96% kinda weird for such a massive battery and such little use. So after 3 minutes of use its down 4%
Now I should mention that I haven't brought it down to empty and then recharged it like how the companies want you to. I understand that with nicad and nmhd batteries but I don't get why lion needs that cycle. But I'll report if there is a difference.
i haven't noticed any difference between my old battery and the new 3500. i let it drain down to 10% and then charged. maybe after a couple of days the rom will adjust to new battery.
Alright 7 hours into the day and i have 80% left.
I'm also kinda liking the extra thickness in terms of using it. Feels about the same in the pocket. A little heavier and easier to feel on a "do I have my phone?" Pocket tap.
One odd thing is the sound from the speaker seems to have improved slightly. I think it has to do with the space between the grill and speaker has a gap and it creates a expansion chamber or something I dunno but it seems to be marginally better.
So 12 hours in now and it's at 57% a definite improvement.
Would you mind uploading some pics please? Maybe a link to ebay. There are a couple of different sellers. Thanks

finally ran out of juice. was playing pocket legends to speed up the process.
here is a link to the auction:

if the link doesnt work anymore the seller was speedy-china http://myworld.ebay.com/speedy-china/
so taking pictures is kinda funny cause typically i use my phone for a point n shoot. i cant find my real point n shoot so ill either look harder tomorrow or bust out my dslr.
I bought the same battery from the same seller a couple weeks ago. I am still waiting for it to arrive. It does take a long time for it to ship from Hong Kong to US, but after reading this post I think my $8.50 was well worth it. It will probably be here in a couple weeks with Christmas slowing the shipping process down and all, but I am eagerly awaiting my purchase.
I bought one a few weeks ago. It does add bulk and a lot of weight however, in my experience it is much more comfortable to hold the phone now. The biggest surprise has been with the new battery case, I can now set my phone down without having the speaker muffled since it is about 1/4" off the surface while streaming tv. I have heard different ideas to break in the phone like full discharge 3 times and others say not to fully discharge it. I would recommend that after your initial charge, turn the phone off and charge it another hour. Personally, I can stream about 5-6 hours of TV (with full screen brightness) at work before needing to recharge.
Any comments like "I took the phone off the charger and it's at 95%" is working as intended. Most phone with Li-on batteries do a cycle charge when they get to 100%. They will stop charge at 100% off charge to 90%, back to 100%, then 90% and so on. This is done because Li-on batteries are dangerous at when under a constant charge. If temperature get too high they can degrade the internal membrane causing fire and explosion from released hydrogen gas.. If you want to leave the house with 100% just unplug and reconnect your phone about 10 mins before leaving.
I got a 3500,not dure if its the same u have. Didnt look at the link
But I got it for emergency. Power goes out... Long trip etc.
I carry 2 other "extended" batts for EDC. Dont mind changing batt and keeping the phone light.

Hey guys, unfortunately I didn't see this post before buying a seidio 3500 and custom case. I just wanted to tell all of you some helpful hints.
1. Condition the battery- run all the way out till phone shuts off (if you go out, keep your original battery and door with you as a backup). Do this about 3 times
2. When charging the light on the Evo turns green after the battery reaches 1500 (the size of the original battery). You need to charge the battery about 3 hours past that to get the full potential of your extended batt. I charge mine over night and I get about a day and a half out of mine!!!
3. It's best to condition the battery about once a month to increase battery life. They say that these batteries don't retain a memory and I believe this to be true, but over my years of experience, it helps to condition very once in a while.
Hope this helps and good luck. Reply back if you get a chance, as I will subscribe to the thread, and let me know if this info helps.
Peace!
How much did you pay for duty fee's to get it shipped here?
im going to average out the difference in battery life of what i have left at the end of the day now vs how much i used to get, to get a good idea of how much more juice im getting.
(so far its looking like 60% more!)

I bought a 3500 on ebay and it was $8.48 shipped. No duty fees. The battery was 2.99 and shipping was 5.49. It is a great deal seeing how everywhere else they are 60 & up.

Battery Life Doesn't Matter

(Personal opinion here, of course.)
I don't care about battery life. The battery on the Galaxy Nexus is removable. When my phone is dead, I swap out my battery for another one. Two batteries gets me through ANY day, regardless of usage patterns. Batteries are small and fit in men's and women's pockets easily. They fit in glove boxes, desk drawers, etc. They're portable, lightweight, compact, etc. You can take them almost anywhere.
I purchased the Samsung battery charger kit and haven't looked back. Instead of charging my phone and feeling tethered to my charger all day, I use my phone however I want and swap batteries in/out as I need to, and I only charge my phone overnight while sleeping now. The rest of the time, I only charge my batteries through the charging kit.
All these threads on battery calibration, battery life, etc. just seem unwarranted to me. I'm used to toting a charger around with me, so now I just bring my battery kit (usually it sits in my car, not needed) and if my battery dies, I swap in a fresh one and charge the spare with the kit. This way, I can have my phone on me all the time without worry. If I have no nearby electric outlet I can still take along the extra battery and charge both batteries later. I actually have 3 batteries, if I need them (I can't imagine ever using all 3 in a day).
I don't even use the extended battery. Why fatten up my phone, even if only by a little, if I don't need to do so?
This is food for thought, that's all. Does anyone else just use spare batteries and no longer worry (or even obsess, as I used to do with my Thunderbolt) over squeezing out every drop of battery life? To me, life is easier and better this way.
There's a name for the feeling of not being tethered to your charger all day. I call it freedom. It's awesome.

I see where you are coming from.. What do you think of the battery cover? Is it difficult to work with when swapping batteries and will it last with such frequent use? How do you make sure that your spare battery is always ready (I guess you must be in the habit of always putting it on a charger)?
The battery cover is easy to remove. I ordered two spares when I ordered my battery kit (door covers are only $3 each) in case they wear out over time, which I doubt will happen. Many days I don't even swap batteries, as my phone typically lasts 10-12 hours on the regular battery anyway. I do charge my phone in the car (why not? my phone would just sit there otherwise) which is ~30-45 minutes a day, enough for an extra 20% charge mid-day which helps my battery hit the 10+ hour mark. And if it doesn't, I just swap for a new battery.
The spare is always ready because I always keep it in the charger kit so I can grab it when I'm in need. The kit has a light which turns green when the spare battery is charged to 100%. The light is red otherwise. It's quite handy.
At night I plug in both my phone and the charger kit using the Y cable charger that comes with the kit (allows 2 devices to charge simultaneously on one charger). In the morning, I have my phone and spare, both ready to go.
May I also say, I've impressed a few of my iPhone-using friends with my spare charger kit. They always say "I wish I could do that, but I don't have a removable battery." I lol every time (silently to myself...)

I completely agree. That and who is really not near a charger ever all day? Maybe a few but hey that's what changeable batteries is for.
I see nothing wrong with improving what we have with calibration and optimization though...
Lol sounds like you are super jaded from using a thunderbolt.
IMHO your logic is flawed. Why not get good battery life on one or two batteries rather than mediocre battery life on two batteries.
You shouldn't have to carry around two batts just to get usability out of our device. Two batteries is for when you demand extra from your device.
Like when I went to New York I carried two batteries for my BB9700. Not because it was a battery hog but because I was GPSing and texting all day and didn't want to be stranded with a dead battery. I ended up using both batteries several times skipping charging both of them one night.

edit: I get great battery life on this phone btw. I love it and am very happy with its performance.
I do the same thing. Have the extra battery with wall charger and just throw the spare in my pocket if I go anywhere. Like the OP stated I would much rather swap out the battery (if/when needed) and be able to use my phone like I want than worry about trying to conserve it all day.
I haven't had any problems with the battery cover and even if it did I can buy a new one from VZW for $3.25 with my discount ($4.99 retail) so it is a nonissue.
I honestly don't know why so few people do this. And I very rarely even end up using the spare battery, I just like knowing I have it if needed.

Agreed. I read that stuff to be informed, but no longer out of a crazy desire to extend my battery life because I can't live without doing otherwise. It's a nice change.
Again, I'm not saying anyone else has to or should do this. But it makes so much sense to me, and I like to share what works for me to help others who are looking for other options regarding battery life.

I'm a realistic type of guy. What I want from my phone and what I get from my phone are two different things. To believe they are the same is literally delusional, by definition. To complain about X Y or Z company not providing me with what I want is also a bit irrational if I know that, given today's technology's limitations, what I want might be asking a bit too much. We must work with what we have. I have spare batteries. I use them, liberally if I need to, and I don't mind doing so.
I don't expect a 4G phone to last all day while I play WWF, browse the web, text constantly, check and compose emails, take photos, transfer data, and make phone calls. To get 3-4 hours of screen on time on one battery is great (to me).
I think carrying an extra battery is being more responsible on my end for my own admitted usage of the phone, rather than complaining that the battery life "sucks" or hacking my phone to get an extra 20% battery life (although I'm not against this at all - it's just more work overall). Instead of blaming Verizon, Google, and/or Samsung, I'm taking ownership of the fact that I use my phone quite a lot, and I'm fine with carrying an extra battery or two. Instead of blaming others for the battery life of my own phone, I take responsibility for it and I provide my own solution. If anything, I'm speaking of personal responsibility. And in said responsibility I've found freedom from the dreaded phone charger. Again, it's a nice freedom to have.

I agree completely with the OP. A second OEM battery and quality wall dock charger are my second accessory purchase with any of my smart phones. The first being a good case.
Having a 2nd or 3rd (or 4th!) battery and/or a charger around shouldn't be a requirement for using your device throughout the day. Sure if you use your phone hard then you're going to be used to having a charger nearby, but it shouldn't be a req if you're a normal user.
I don't think its unreasonable to expect a normal (12 hours) days use out of a device. FWIW most people are getting that (especially GSM users), and I don't think the battery issues are as widespread as people seem to think. There are "omg batterylife" threads in every new device forum.

I often go a full day without seeing a charger. Sure I could carry one around and hunt for outlets throughout the day, but I don't think that should be a concern. Just want the phone to be reliable.
For what it's worth, I bought an external charger a couple phones back. Just plug in via USB to the phone if it's running low. Really useful when I'm on the train, for example, and I tether wifi for my Xoom. Gets me through the day in a pinch and I don't have to buy a new one with every phone (though I might buy a larger one now given the Galaxy Nexus' bigger battery).
Also, I usually plug the phone in while at my desk and always charge overnight. But I use the hell out of my phone

I have to agree with Martonikaj I'm afraid. Its a phone, just because you CAN swap out the batteries doesn't mean you should HAVE to to get reasonable usage life.

I disagree with the OP for having 2nd, 3rd batteries in order to use it properly based on user usage pattern.
First, define your usage pattern then try to optimize the battery to support that.
My usage pattern requires to have at least 3 and a half our screen time, and charge the phone once every two days, before I went to sleep (or during the night).
And this phone battery can do that without any problem ...
So, I don't need second battery ... and I am ordering the 2000mAH extended battery for GSM model. Having extra 250mAH is nice, it's a bonus for additional 30 minutes screen time! ... while still having the same look and thin device profile
Hey guys can someone recommend a good place to buy a second battery and charger if needed? Is it worth getting the extended battery and do I need to buy a different back cover if I purchase one? I am in Australia so was thinking eBay might be my best bet? Cheers
I do the same as the OP. I have three batteries that I rotate through. The OEM Samsung battery that came with the phone and two 1900mah batteries that I bought from eBay (which aren't too bad by the way) . I don't ever have to plug in my phone anymore because most of the time I have two fully charged batteries ready to go. I get on average between 12-15 hours on a single charge as it is with pretty good use, so I'm not worried about my phone dying, its just more convenient.

The best battery I used was 2 evo4g 1900 mah batteries for 7$ on eBay. The battery lasted 2 days with decent use but unfortunately I could not get it to charge with the phone on any rom... even though the polarities looked the same as our batteries.. if only..

I bought the 4$ OEM off eBay and it was worse than my already dying battery.

Yea the $4 one came in yesterday and after 36 hours I can tell it's not as good as the original oem. It's not horrible and will serve as a decent backup.. but certainly not a DD battery.. no way.
I'm more curious to give the 3500 a spin. Hopefully that arrives today.
Can't wait to hear about the 3.5Ah!
I have a 2.2, I think. Probably could last me three days if I didn't surf and play so much.
Edit -
I should mention that I usually end the day with about 50% left.
Today I'm already at 14% at 6pm because I watched two hour-long videos and did all the other surfing stuff as well.
Curious what you use to test your batteries with.
I run Battery Monitor Widget Pro and always wipe stats for a new battery. Great app for tracking battery performance.

Sorry, I haven't been able to test much. The performance was so crappy the few times I did use it that it hasn't left my shelf ever since. I know I said I was going to do standardized tests but I've been super busy the past few weeks.
As for the anecdote- I charged the 3500 up to 100% and went out for a night on the city at about 2pm. It was dead by 11pm and I was pissed. However, I'm not willing to pass judgement on it yet because I was running PAC at the time which absolutely devoured whatever battery I used.
Now that I'm back on stable CM7 it's a bit different. I'll charge her up tonight and do some comparisons this weekend.
In my experience a battery needs to be exercised a few times before it "matures".

You're probably right. I'll have some more definitive results on Monday.

I bought a cheapo battery for my G1 from my favorite cheapo Chinese stuff website - dealextreme.com.
I think I got an extended battery for my OG Droid there as well, long time ago. They were ok.
I absolutely love big batteries. And paying as little as possible for them.

So I don't have any definitive results. Overall the 3500 does last longer but not by much. I ran it from 100 to 1 twice over the past week and made sure it received standard use and no charges. I have attached 2 screenshots of the drain plus one with the top culprits for drain. Like many 3rd party batteries it tends to take a nosedive once reaching ~18%. You have maybe 10 minutes left when it hits that mark.
My workplace has horrible signal so cell standby is probably much higher for me than it would be for most. For comparison, my OEM lasts about 14-18 hours without a charge.
Bottom line:
3500 mAh linked above- You can't go wrong for $9. It performs like a ~2500mAh. the case is good quality too.
1500mAh linked above - might come to the range with me next time for target practice. That thing is worthless and is maybe good for 4 hours of standard use. Streaming a 1 hour playlist from Google music used approximately 40% of the battery.
Good to hear.
It's sad that we can't trust the ratings on the batteries, but I am glad it worked as well as it did and that the cover was acceptable, too.
I've read a lot of battery reviews on Amazon and even then it's a tough decision to make. Like you said, for the $9 it's ok.
I'll never buy a $50 battery, but if I did I would certainly expect it to perform to the advertised spec. Sadly, the reviews on those batteries are as mixed as the reviews for the cheapies.

Some interesting information
Bought similar battery a few months ago. On standart battery I has only 10-15% left at evening (music, instant messaging and serfing drains battery wery well), with this enhanced battery my phone lasts 2-3 days. I attached the photo to compare it with default battery.
The main disadvantage of it, suddenly, was the incredibly low signal level (only 1 bar on WCDMA in wooden house, 2-3 bars on GSM), problem was in antenna that is located at the down of back cover. As you can see, two contacts was joined. Just split them, and signal should improve. It helped me, but not too noticeably. So, I have to put copper wire on the back cover and even to prolong it beyond. It looks very ugly, but now signal level is even better than on stock battery (always full signal level on the street even in 3G mode). Low signal level results in higher battery drain and heat.
I don't know why HTC decided to save money on antennas in our phone. Because stock battery cover GSM-antenna is worse than any Nokia (it's much smaller, but in antennas, size matter, a lot). Wi-Fi antenna is bad too.
Also, battery indicator in our phone is not works as it should, I think. 0% is actually not zero level. Real Lithium-Ion battery zero level is 3.2-3.3V (sometimes even smaller, but it's not recommended to to discharge it beyond this level, it may damage battery), but HTC controller tells 0% at 3.5-3.6V and Android forcibly powers off the phone. When I used De-Sensed V firmware, where Android power off function on zero battery level not worked (may be, it was disabled in services.jar, there is the way to do this thing), I could run up to one hour in ICQ on 0% and even some hours in idle mode, before the battery controller blocked battery discharge to protect it (voltage was around 3.2V). It's disappointing that I can't make an urgently call while I actually have the power level enough to do this.
Thank you! Very nice to read your solution for the antenna!

I have good luck with my antenna, so I doubt I will have to do any fixing.

AckerMAN_ can you give more details about your antenna fix?
I see in the photo that the cover has two plastic fingers that are painted with copper colored paint.
My cover has metal fingers attached to it for the connection. They are like springs.
Can you attach a photo of your antenna wire, please?
This phone is famous for poor signal and many others would be interested in a way to improve reception.

There is a photo of back cover with attached wire. Also, I attached the screenshot of current reception level. I hope it will be useful.
Also, I'm thing about patching services.jar, I'll try it when have enough time.

portable battery pack with solar panel?

im looking to buy a backup battery pack( the external portable battery)
not sure what the proper name for it
is there a battery pack that can last me 5-7 hours of continuous use ( for example on an airplane or camping) watching movies etc
i saw some at the airport on best buy vending machine but they were kinda expensive
so is there one with solar panel
and if there is one what is the best band for the buck
capacity. solar charging speed etc
somewhere in 60-150 dollar rance maybe?

The one with solar panel is a joke. You need direct sunlight and it will be charging for a day, waste of money.
You are looking for external battery. Those are inexpensive, I reviewed a ton of those (did you see a sticky at the top of the forum with all my reviews?). Or you can check out link directly from my signature.
Best one, the most popular brand on amazon hundreds/thousands of 5-star reviews, which I have reviewed is by Anker. For what you are looking, you should get the highest capacity which is also compact enough for traveling. For $50 you either get new gen Astro 3, 12000 mAh (http://www.amazon.com/12000mAh-External-Battery-Technology-Smartphones/dp/B00CEZBKTO/) or older Astro E5, 15000 mAh (http://www.amazon.com/15000mAh-Portable-Ultra-High-Capacity-External/dp/B00D5T3QK4/). Don't know what phone you have, but most likely these will be 6x-7x capacity of your phone battery. So we are talking about at least a day or so of continuous use with your phone Read my reviews to find out which one you like better.
thanks man i didnt even know they could go that long i was expecting 4-6 hours of continuous use.
i have galaxy s3 right now
and with that in mind i wanted the solar panel so i can leave it trickle charging while its sitting unused.
i dont plan to use it every day just when im away from charger on long trips when using navigation or airplane and such.
or camping for several days with no electrical outlets around
how bad is the solar charging on them
can yougive me an idea for example if i would leave it in the sun for a day ( sunny day)

From everything I've read, you have to leave it in direct sunlight for many hours just to recharge it back to 50%. Almost doesn't seem worth it.
Here is one i'm thinking of trying.
G power, power bank power modular.
power bank with 6000mAh upto 42000mAh or more, with included solar panel charger on the move.
ignore the 20 second advertising in the video.

I have a battery pack with solar...Useless I will say. Charging the pack goes quicker on direct ac than leaving it in the sun, charges extremely slow. I regret purchasing and does not even hold a charge that long.
