The Vivo S1 battery model name is B-H0 in the replacement listings seen, and the capacity is 4500 mAh. The phone is sold under model number 1907, which some listings write as V1907. Most people type the code as BH0, B-H0 or even BHO, and all of these point to the same pack. Watch the last character: it is a zero, not the letter O.
This page is for the phone itself. If you are at a counter with a Vivo S1 in your hand and do not know what to ask for, start with the model number and the code above. No twin phone is confirmed for this code, so the label on your own old pack is the final word before you buy anything.
Quick facts
Step by step
Read the model number first
Open Settings, tap About phone and note the model number. If you cannot find it, type model in the Settings search bar. It should read 1907 or V1907.
Compare it with the retail box
The box label usually repeats the model name and number. If the box is gone, the model number from Settings is enough to start.
Have the back opened by a technician
The Vivo S1 is a sealed phone, so only a technician should open it. Ask them to read the cell label and say it aloud:
B-H0is what you expect.Match the connector before fitting
Put the new pack next to the old one. The code, the connector end and the pack size should all agree before anything is plugged in.
Vivo S1 battery model name: what the listings say
The Vivo family writes its battery codes as the letter B, a hyphen and two characters. For the Vivo S1 the listing seen gives B-H0, with a capacity of 4500 mAh, and ties it to the names Vivo S1, 1907, V1907 and V1913A. That is one source style only, so treat the match as likely, not as settled. The letters in a code never name a phone on their own.
| Item | What the listing gives | Status |
|---|---|---|
| Battery code | B-H0 | Seen in replacement listings, check your label |
| Model number | 1907 or V1907 | Same phone, written two ways |
| Other model name | V1913A | Appears in the same listing, not explained |
| Capacity | 4500 mAh | Matches the advertised figure for the phone |
| Twin phones | None named | Not confirmed |

Phone name S1 and code B-S1 are not the same thing
Many buyers search "s1 battery model name" and then land on a code that begins with B-S. That is a trap. The S1 in the phone name is a marketing name. A code such as B-S1 is a battery label, and it belongs to its own list of phones. Having S1 in both does not mean they match.
One customer asked for an "S1 battery" and the shop reached for a B-S1 pack. The technician opened the Vivo S1, read the code on the cell, and refused the swap. The names looked alike, but the codes did not match.
If you want to see what B-S1 really belongs to, open its own page. Do not carry its phone list over to the Vivo S1.
Where to see the Vivo S1 battery model name: box, Settings and cell
Your phone shows its name and model number openly, but the battery code is a different matter. Settings and the retail box give you the phone model, not the pack code. B-H0 appears only on the S1 cell label and on parts listings. On a sealed phone like this, that means the back must come off first.
- Box or About phone: gives the model number 1907.
- Parts listing: gives the pack code for that model number.
- Cell label: confirms the code, and usually shows the capacity as well.
If a shop only says "S1 battery" with no code, ask for the code and the model number in plain words. The general approach lives in our guide to reading pack labels.
What 4500 mAh means on this phone
The figure of 4500 mAh is what the maker advertises and what parts listings repeat. The S1 cell may print a rated minimum slightly under 4500 mAh. Both are normal. A pack that claims far more than 4500 mAh in the same body is the one to doubt.
Watt hours equal mAh times volts, divided by 1000. No voltage is confirmed for B-H0, so read it on the S1's cell sticker. As an illustration, a pack labelled 3.85 V would store roughly 17.3 Wh at 4500 mAh. Use that sum to compare two packs honestly, because equal mAh at a different voltage is not equal energy.
The S1's screen time depends on its AMOLED display, signal, brightness and apps. How quickly the S1 recharges depends on the adapter and the temperature, not only the B-H0.
Is your Vivo S1 battery wearing out?
| vivo S1 sign | Why it happens | B-H0 action |
|---|---|---|
| Half a day of use leaves you at one digit | B-H0 has aged and lost capacity | Check S1 health, then plan a B-H0 |
| S1 goes dark near a fifth charge | Worn cell sags under load | Have a technician test it |
| Screen lifts from the frame | B-H0 swelling and pushing outward | Stop charging, get it checked today |
| S1 runs warm at rest | A background app or tired B-H0 | Restart the S1, remove its cover, watch it |
On an S1, rule out apps and a weak network using our drain troubleshooting page before anything else. To measure the wear itself, try the step by step health test.
A swollen, hot, leaking or dented pack can catch fire. Disconnect the S1, avoid squeezing or flexing it, and keep it far from heat. Cheap copies often print a capacity that no cell of that size can hold, so accept a replacement only when its code matches the one on your own old cell label.
Fitting a new pack: keep it simple
The Vivo S1 has a sealed body, so let a professional do the opening. Give the technician the phone name, the model number 1907 and the code B-H0, and ask them to compare it with the old cell before they fit the new one.
A weak B-H0 copy gives itself away like this:
- It feels obviously lighter than the S1's original B-H0.
- The B-H0 print is blurred, without a batch code.
- Its sticker claims far more than 4500 mAh.
- The connector end is a different size or shape.
Take a photo of the old cell label before it goes in the bin. That way a mismatched first pack does not force a second opening of the S1.
More on choosing a route is in the replacement guide. Another Vivo phone with its own pack is covered on the Vivo V20 page if you are comparing.
Looking after an ageing S1 pack
The Vivo S1 is an older phone now, so its cell has probably gone through many charge cycles. Heat is the biggest enemy. Keep the S1 off soft furnishings, out of a hot car and out of strong sunlight while charging, and peel off a heavy case once it warms.
Charge the S1 with its boxed adapter or one rated similarly, and replace a lead that warms at the plug. Try not to leave the S1 sitting at 100 percent all night, every night. If it still shuts off at a fair charge level after a restart, the cell is the likely reason, and a new pack will help more than any setting.
Frequently asked questions
What is the Vivo S1 battery model name?
The listings seen give B-H0, a 4500 mAh pack, for the Vivo S1 with model number 1907. Always read the code on your own cell label before you order.
What capacity is the vivo S1's B-H0?
The phone is advertised with 4500 mAh. Your B-H0's sticker may print a rated figure just under that.
Is BH0 the same as B-H0?
Yes, people drop the hyphen when typing. The last character is a zero. If a listing spells it BHO with a letter O, ask for a photo of the S1 label.
Can I fit a B-S1 battery in the Vivo S1?
Do not assume so. B-S1 is a different pack; the S1 in both names is a coincidence. Match the code on your own old cell.
Can I change the Vivo S1 battery at home?
The vivo S1 is sealed, so opening it calls for tools and patience. A brand service centre or a good local technician is the safer route.
How do I find the model number of my Vivo S1?
Go to Settings, then About phone, and look for the model number. If you do not see it, type model in the Settings search bar.
