Application:
As we know, for iPhone XS and above models, when a third-party battery or a genuine replacement battery is replaced by a third-party repair shop that isn't one of Apple's authorized partners, the battery health menu will show a warning about being unable to verify this iPhone has a genuine iPhone battery. The solution for this kind issue is to swap the original battery protection board to the new battery. This spot welder can be used to solder the battery protection board to solve this problem.

Instructions:
1. Power on/off.
Press and hold the power button for two seconds in the shutdown state, the light goes on and the device turns on.
Press and hold the power button for two seconds in the power-on state, the light goes off and the device shuts down.
2. Switch output mode.
The welding output is started after the device is turned on, and the output mode can be switched by pressing the power button once. There are two output modes available:
Automatic output: The spot welding pen is automatically detected and outputs once when both welding pens are detected to have touched the metal.
Manual mode: press manual spot welding button for one second, the spot welding pen will be output once.

Note:
1. In cold weather conditions, battery performance may be reduced, warm up more than a dozen solder joints, and can restore performance. It is best to use in a warm room, charging to be timely, low-charge shutdown, can be recharged and reawakened.
2. If placed for a long time, the device needs to be fully charged and charged every two months. If the device has entered deep sleep mode, the voltage is reduced to no power, please contact customer service to learn how to wake up.
3. Please do not disassemble the host or replace the battery by yourself.

Amazing, but gigantic. Gave to my partner.
Color: Summer Sweetness, Size: 40 Ounces
5 stars because I got this bottle on sale for the same price as the 30oz, the colors are *gorgeous* and every bit as vibrant as the image shows (which I'm seeing is not typical across the board for owala) and it is indeed just a fabulous, strong water bottle. Easy to drink from the built-in straw, a joy to carry, and fits in every cup holder so far. I've already adapted better hydrating habits compared to using my old daily Nalgene. However, I am 5'5 and wanted a bottle to carry around frequently for work. This thing is like as big as my thigh bone lol! I should have gone to a local Target or Academy to compare the 30oz vs the 40oz bottle because the size difference is significant. If you consider the added weight for a full 40oz, I set myself up for failure in terms of my needs for this bottle. My 6'2" boyfriend who loves colors and works outside all day was happy to adopt this one for me however, and I ended up purchasing a 30oz elsewhere in equally fun colors. We have both had success having ice last a full workday. His keeps cold in the car and mine usually has a good bit of ice still after 3 refills and constant use. So far so good on no-spills, and I really appreciate the lock mechanism as I work around delicate artwork all day. It would be nice if the cups were machine washable alongside the gaskets, lid, and straw-- but alas, it's easy enough to clean in the sink and probably wouldn't fit in a top rack anyway. Each bottle comes wrapped with beautifully thorough care and use instructions as well-- take the time to read it all! Overall, I would recommend this cup 10/10. Cold water all day and a built in straw have changed my daily water intake by and large-- so if you're looking to better your hydration habits, look no further and don't overstep your needs like I did if you work around available water spouts all day... The 30oz is enough.

💯 stars - Best water bottle on the market!
Color: Off Road, Size: 30 Ounces
Lots of tumblr love for this Owala bottle... It's pretty much perfect! I ordered this brand after getting my grandson a kids Owala cup that has proven to be basically indestructible and that's saying something because a 2.5 year old will put something through it's paces. That cup is over a year old now and still going strong. Visually - it's lovely, the color is exactly as pictured but this thing isn't just a looker. She delivers in every way. The tumbler isn't round toward the top, it has these straight edges which makes it easier to grip. the handle is just high enough to hold it w/out being uncomfortable or knocking my knuckles on the spout or top of the bottle. the lock lever behind the spout is nothing short of genius (As any of us know that have 'thought' we closed out tumbler only to have it leak on our computer inside out backpack...) (<-- I'm not the only one, right?) The 'swig or sip' lid is probably my favorite feature. Generally I've preferred a straw-type lid but no more, this lid offers a great drinking experience. This bottle does what it's meant for - keeps things hot or cold for ages. I mainly use it for cold beverages and it does not disappoint. My elderly dad was recently in hospital and I loaned my bottle to him because it was so much easier for him to use than a cup w/ a straw. Needless to say, I'll never see that bottle again. He loved it. I'm now ordering myself another. It's an investment for sure but it will deliver years of use.

Quite literally my perfect water bottle
Color: Black Cherry, Size: 40 Ounces
This water bottle is perfect for me and is absolutely everything I wanted in a water bottle. Easy to clean, not too heavy and the handle makes it easy to carry around anyway, keeps water cold for a day but not much longer than that (but that's okay). I haven't dropped it yet so I don't know how well it'll hold up when I inevitably do but it seems plenty sturdy to handle it. I'm so excited about the color too because it's my favorite color and from what I can tell the dark cherry is an Amazon exclusive so I'm glad I found this. I love that it's still slender and can fit in standard cup holders while being a bigger bottle holding 40oz, which was my biggest priority. I've never had an Owala before so I wasn't sure what I'd think of the freesip mouth but I love it. I don't usually need to chug but having the option is nice too! If I ever need to replace this beauty I'll definitely get another Owala. I really could not ask for a more perfect water bottle. I don't even usually write reviews but I love this thing so much I just had to. I usually wouldn't spend this much on a water bottle but given all the praise I have for it the price is perfectly reasonable to me (and I try to be smart with money and responsibly pick when to spend more on something or be more frugal.) This is definitely worth the higher price than I have spent in the past on water bottles, and I'm pretty confident it'll last me a long time anyway, and I use it every single day too.

Best Water Bottle Ever!!
Color: Strawberry Fields, Size: 40 Ounces, Color: Strawberry Fields, Size: 40 Ounces
This is the greatest water bottle ever! I ended up buying 2 more after this. First, it's 40oz in a very easy to hold cup, that fits into car cup holders. It's leak proof which is amazing because every other bottle I've tried leaks in some way. You have 2 ways of drinking. You have the straw, and also the sip option. The handle is strong and sturdy. It locks to make sure it won't open on you on accident. Overall this is the greatest bottle I've ever had, and I'd highly recommend to anyone looking for a great bottle!

Doesn’t leak, durable, keeps drinks cold
Color: Sparkling Sherbet, Size: 40 Ounces
Absolutely love this water bottle. I am a water bottle junkie and this one is my favorite. It doesn’t leak and the fact that I can guzzle or sip through a straw is a major plus. It is kind of heavy but it is a big thermos. The only reason I didn’t give five stars is because the bottom doesn’t fit in all cup holder. It keeps my drinks cold all day and is super easy to clean. It is very sturdy and well made. I figured after using for a while, the lid wouldn’t pop open as easy as it did when it was new, but it still does. I also love the lock feature incase the button accidentally gets pressed when I am carrying it around in my bag.
